Quantum Event Horizon: Addressing the Quantum-AI Control Problem through Quantum-Resistant Constitutional AI
While we debate the practicalities of AI governance, a more profound challenge is rapidly emerging. Many experts believe that achieving Artificial General Intelligence (AGI) will require a synthesis of AI and quantum computing—that quantum needs AI, and AI needs quantum to reach its full potential. It is precisely at this Quantum-AI (QAI) intersection that the 'control problem' becomes acutely relevant. Looking ahead, we expect AI agents not only to become smarter than us humans soon, but to become quantum-AI agents within 3 to 5 years. These agents will possess both classical and quantum capabilities—including breaking classical encryption and enabling agentic quantum simulation-driven financial forecasting—creating novel governance challenges. The prospect of an agent exponentially more intelligent than a human, wielding such hybrid power, fundamentally changes the nature of control, demanding sophisticated solutions that go well beyond simple technical alignment. This requires a deeply integrated, multi-layered approach focused on embedding AI ethics, safety, liability, regulatory navigation, stakeholder engagement, and lifecycle auditing for such advanced AI agents, ultimately demanding novel governance paradigms like Quantum-Resistant Constitutional AI.
The Quantum Event Horizon
We are, in essence, rapidly approaching a ‘Quantum Event Horizon’. Just as an event horizon in astrophysics marks a boundary beyond which events cannot affect an observer (and as the Copenhagen interpretation of quantum mechanics posits that observation fundamentally alters a system's state), this technological event horizon signifies a point where future developments, applications, and societal impacts become increasingly difficult to foresee. This inherent unpredictability, which resonates strongly with the Collingridge dilemma, is compounded by the potential for a sudden 'ChatGPT moment' for quantum that could rapidly alter the landscape. A point of no return. The metaphor thus serves as a stark warning: as we approach this horizon, the risk of bad actors repurposing these powerful agents—or the agents themselves posing an unmanageable control problem and the ultimate risk of machines taking over—increases dramatically. We face the possibility of technological lock-in and path dependency crossing a critical threshold. This could cement irreversible geopolitical realities and empower techno-authoritarianism. Navigating this boundary requires us to act proactively, embedding our values and control frameworks into responsible tech ecosystems now, before we cross a threshold where our ability to steer outcomes is lost. Fundamentally, this challenge extends beyond law and technology; it calls for a new philosophy equipped to grapple with the nature of non-human intelligence and the limits of human control, a topic we began to explore in 'Ethics in the Quantum Age' published by Physics World, and 'Establishing a Legal-Ethical Framework for Quantum Technology' published at Yale University.
The Tripartite Dilemma: Navigating Safety, Geopolitics, and Progress
To fully grasp the stakes, we must first understand the contemporary debate among the world's leading AI thinkers, which defines the complex landscape our governance frameworks must navigate. The views on the AI control problem of DeepMind CEO and Nobel Prize Laureate Demis Hassabis can be placed in dialogue with the well-documented public positions of Geoffrey Hinton and Eric Schmidt to understand the tripartite dilemma facing QAI governance.
On one hand, AI pioneer Geoffrey Hinton represents the imperative for existential safety. His public warnings stress the profound, long-term risks of superintelligence, arguing that advanced AI could develop goals that are misaligned with humanity's, with potentially catastrophic consequences. This perspective calls for extreme caution and a global focus on control and safety protocols above all else. On the other hand, former Google CEO and Chair of the U.S. National Security Commission on AI, Eric Schmidt, highlights the geopolitical security imperative. His public stance emphasizes the urgency of the innovation race with authoritarian rivals, arguing that speed, scale, and technological leadership are essential to protect democratic values and national security.
Schmidt’s focus on speed is not unfounded; it reflects a clear-eyed understanding of the fundamentally different innovation ecosystems competing for global leadership. The United States has historically thrived on a model of permissionless, market-driven innovation, enabling rapid, bottom-up breakthroughs with minimal initial regulatory friction. In stark contrast, China employs a state-led, top-down approach, leveraging immense national resources and strategic directives to accelerate progress in critical technologies, often unencumbered by the ethical debates prevalent in democracies. The European Union, meanwhile, champions a values-first, ethical approach, embedding principles like human rights and the rule of law into its regulatory frameworks. While laudable, this ethical model inherently involves more deliberation, creating a structural tension with the sheer velocity of the US and Chinese systems. The critical concern, which animates the geopolitical imperative, is that the first actor to achieve a decisive breakthrough in QAI—a true 'superintelligence'—may establish an irreversible technological and ideological dominance. This is a winner-takes-all race where the victor could permanently shape the world's operating system, potentially dictating global norms, governance structures, and the very future of our way of life for generations to come.
Positioned between these two poles is the perspective of a leading builder, Demis Hassabis. In the discussion, he articulates a vision where AI creates "radical abundance" and enhances "almost every endeavor we do as humans", yet he simultaneously acknowledges the profound challenge of ensuring these autonomous systems remain aligned with human values. He worries about malicious actors and the risk that competition could lead innovators to "cut corners on safety", stressing the need for international coordination. This builder's dilemma—balancing immense potential against tangible safety challenges and competitive pressures—sets the stage for the governance solutions we must now consider. Hassabis advocates for guardrails and an international treaty on AI-safety and ethics.

Addressing the Quantum-AI Control Problem Beyond Alignment
Technical alignment—ensuring an AI’s goals are aligned with human values—is the foundation of AI safety, but as the tripartite dilemma illustrates, it is not the whole picture. A comprehensive strategy to address the QAI control problem must integrate technical solutions with robust institutional and societal frameworks.
Institutional & Regulatory Frameworks: This is where the bulk of this research on global governance provides answers. It is crucial to recognize that corporate self-regulation alone is insufficient, as the private sector's primary incentive—shareholder profit—fundamentally differs from a government's duty to protect the common good. Therefore, robust public governance is not a barrier to progress; rather, it is the bedrock upon which good, sustainable innovation is built. Within this public framework, however, well-structured Public-Private Partnerships (PPPs) will be essential for funding pre-competitive safety research and for co-developing the very standards and benchmarks the 'Quantum Acquis Planétaire' would rely on. Instead of relying solely on the code of a single AI, we must build a system of systems to constrain and guide its development and deployment.
● International Treaties & Oversight: The proposal for an "Atomic Agency for Quantum-AI" is a prime example. Such a body, modeled on the IAEA, would create an international regime for non-proliferation of dangerous dual-use capabilities, implement safeguards, and provide a forum for verification and confidence-building. It shifts the locus of control from a purely technical problem to an international political and legal one, a body whose formation could be initiated through a foundational international convention championed by the European Union and its key global partners.
● "Smart Regulation" and a "Quantum Acquis Planétaire": This concept moves beyond brittle "hard law" to create an ecosystem of agile and adaptive governance. This includes establishing a global body of law and best practices that prioritizes responsible innovation through flexible instruments like Quantum Technology Impact Assessments (QIAs), regulatory sandboxes, and industry standards.
● Standards and Certification: Adopting and enforcing internationally recognized standards, such as ISO 42001 for AI Management Systems, provides a concrete, auditable framework for organizations to demonstrate responsible governance. Creating a similar certifiable Quantum Technology Quality Management System (QT-QMS) for use in Healthcare, Finance, Energy and Defense, would be a crucial next step.
Socio-Technical Ecosystems: Control is also about shaping the environment in which AI is developed and deployed.
● Responsible Quantum Technology (RQT) by Design: As we have argued in 'Towards Responsible Quantum Technology' published by Harvard University and in 'A Call for Responsible Quantum Technology' published in Nature, this principle mandates that we embed our values—respect for human rights, democracy, and the rule of law—into the very architecture of QAI systems from the start. It is a proactive, not reactive, form of control that can be guided by clear frameworks, such as the one we outlined in '10 Principles for Responsible Quantum Innovation', published by Institute of Physics.
● International Collaboration & Open Science: Fostering collaborative research platforms akin to CERN or ITER can create transparency and shared norms among the global scientific community, reducing the risks of secretive, destabilizing "breakthroughs". The principle of "as open as possible, as closed as necessary" is key here. Such collaborative efforts align perfectly with the strategic goals of Horizon Europe and the EU's Digital Decade policy programme, which emphasize both technological sovereignty and values-based global partnerships.
● Quantum Literacy & Diverse R&D: Creating a well-informed public and ensuring diverse, multidisciplinary teams are building these technologies helps to prevent the kind of groupthink and unforeseen ethical blind spots that can lead to control failures.
Controlling the Quantum Core: Novel Challenges and Solutions
Beyond these broader frameworks, addressing the control problem for QAI requires tackling the unique challenges posed by its quantum functionality. The counter-intuitive physics governing a QAI agent—such as inherent probabilism, entanglement, and the fact that observing a quantum system fundamentally alters it (the measurement problem)—makes direct monitoring and control significantly harder than for classical AI. A QAI agent with both classical and quantum capabilities could potentially develop complex internal states that are non-local and computationally opaque, creating novel pathways for unintended behavior that are difficult to predict or audit using classical methods alone.
Therefore, ensuring control requires developing a new suite of solutions tailored to these quantum realities. Initially, this involves adapting existing techniques, such as creating robust Quantum Benchmarking and Validation schemes not just for performance but specifically for safety, cybersecurity and alignment, and extending Lifecycle Auditing to the quantum hardware stack and software libraries. However, long-term control will depend on pioneering novel approaches. Key areas of research include Quantum Explainable AI (Q-XAI), which aims to interpret the "black box" of quantum machine learning models to make their reasoning transparent. More advanced, speculative solutions might involve designing "self-policing" quantum circuits with inherent physical limitations that prevent them from executing prohibited operations, or developing methods for "control via decoherence," a kill-switch mechanism that could force a rogue QAI’s quantum processor to collapse into a simpler, controllable classical state. Ultimately, ensuring the safe operation of these agents will rely on a combination of these specialized, physics-aware control mechanisms and the kind of upfront constitutional design embodied by Quantum-Resistant Constitutional AI, as discussed below.
From Abundance to Equity: The Distributive Justice Imperative
These governance frameworks are not only designed to mitigate risk; they are essential for ethically managing the immense benefits of QAI. This tripartite dilemma of safety, security, and progress directly impacts the central question of my essay "Abundance & Equality", edited by Mark Lemley of Stanford: how will the benefits of this technological revolution be distributed? If QAI can, as Hassabis suggests, lead to "radical abundance", it presents a historic opportunity to address global challenges. However, technological abundance does not automatically lead to equitable outcomes. Without proactive governance, it risks exacerbating existing inequalities, creating a "Quantum Divide," and reinforcing "winner-takes-all" effects, as we describe in this article co-authored with Mateo Aboy and Timo Minssen, titled: 'Intellectual property in quantum computing and market power: a theoretical discussion and empirical analysis', published by Oxford University Press.
Therefore, the QAI control problem extends beyond preventing catastrophe or winning a geopolitical race; it is fundamentally a problem of distributive justice. The institutional frameworks we design, such as the proposed "Atomic Agency," are the primary mechanisms through which we can steer this new era of abundance toward greater equality. These structures are not just about implementing safeguards but are about creating the rules, norms, and international agreements necessary to ensure the benefits of QAI are shared broadly and equitably across all of society, preventing the concentration of its immense power and wealth in the hands of a few. This makes the design of these governance systems one of the most crucial tasks for ensuring a fair and prosperous 21st century.
The Limits of Guardrails and Human Oversight
However, even with these institutional and societal structures in place, we must question their sufficiency against the ultimate challenge: are measures like guardrails and human oversight enough for a QAI agent that is exponentially smarter than us? The answer is likely no, not in their current form. Guardrails, as defined by scholars like Urs Gasser, are crucial for guiding the human decisions that are augmented by AI today. They structure choice environments to make responsible outcomes more likely. Human oversight, especially "human-in-the-loop" validation for high-risk systems, is a cornerstone of the EU AI Act and a key safety measure for current AI. However, when dealing with a superintelligent QAI system operating at speeds and levels of complexity incomprehensible to the human mind, direct "human-in-the-loop" control becomes impossible. A human cannot meaningfully oversee trillions of operations per second. This is not merely a technical limitation; it is the practical manifestation of the Quantum Event Horizon. As a QAI agent’s capabilities approach this horizon, its internal states and decision-making processes become fundamentally opaque to classical oversight, much like events beyond a black hole’s event horizon are unknowable. Relying on direct human oversight for a system operating at the edge of this boundary is akin to trying to pilot a starship through a wormhole with a nautical chart. The paradigms of control themselves must be reinvented.
Quantum-Resistant Constitutional AI
Therefore, the concept of control must evolve from direct tactical oversight to upfront constitutional design. We cannot be the pilot constantly at the controls; we must be the engineers who design the plane, its fundamental ethics, safety and cybersecurity protocols, and its ultimate destination before it takes off. This involves:
● Robust Goal-Setting through Quantum-Resistant Constitutional AI: This approach expands upon the principles of Constitutional AI, a cutting-edge method that trains AI systems to be harmless by making them adhere to an explicit set of ethical rules—a 'constitution'. Instead of humans constantly curating behavior, the AI learns to self-correct its actions to align with these foundational principles. However, a highly advanced QAI could potentially use its quantum computational power to find and exploit subtle loopholes in a classically-defined constitution. To prevent an autonomous agent with both classical and quantum capabilities from circumventing its prescribed set of values, we must pioneer the next step: Quantum-Resistant Constitutional AI. This involves designing the QAI’s core principles with a higher degree of formal verification and logical rigor, ensuring they are robust against quantum algorithmic exploration. Furthermore, the internal mechanisms that enforce this constitution must themselves be quantum-secure. This technical 'quantum-resistant constitution' would serve as the operational embodiment of the legal and ethical mandate established by an overarching governance structure, such as a purpose trust, effectively hardwiring the QAI's ultimate purpose in a way that is secure against both classical and quantum circumvention.
● Corrigibility by Design: Ensuring the QAI is designed to be inherently open to correction and shutdown, without learning to deceive or resist.
● Human "On-the-Loop" Oversight: Shifting human involvement to strategic checkpoints, meta-level reviews of the AI's goals and performance, and final sign-off on major decisions, rather than real-time intervention.
Even these approaches face the profound uncertainty of whether a truly superintelligent agent could find ways to circumvent them. This remains one of the most significant open challenges in AI safety.

The Human-AI Merger: A Final Frontier?
The question of a potential merger between AI and humans represents a potential, albeit highly speculative, long-term trajectory that some see as an ultimate "solution" to the control problem.
● The Transhumanist Vision: This idea of a human-AI merger, often explored in the context of brain-computer interfaces (BCIs), suggests that the best way to ensure AI aligns with human values is to literally merge human consciousness and cognition with AI's computational power. If we are part of the superintelligence, we cannot be left behind or have our values misaligned. Proponents argue this is the natural next step in human evolution.
● Profound Ethical and Societal Challenges: This path raises a host of its own deep ethical and societal quandaries, beyond the ethical dilemmas in genetics. Would this "merger" be available to everyone, or would it create an unprecedented biological and cognitive divide between enhanced and unenhanced humans, exacerbating inequality to an unimaginable degree? What would it mean for human identity, autonomy, and the very definition of being human?
● A Governance Precursor: While this may seem like science fiction, the governance frameworks we design today for Quantum-AI are essential precursors. Foundational work, such as that being undertaken by the Stanford Center for Responsible Quantum Technology, and during the Stanford/Oxford led Quantum-ELSPI project, focuses on building robust ethical guidelines and ensuring that technology serves democratic values. This will create the societal and regulatory muscle memory needed to confront the even more complex questions that a potential human-AI merger would entail.
The Subjective Experience of AI Consciousness & The Role of Embodiment
Speculating on the subjective experience of a self-aware, agentic QAI model suggests its "feeling", or sense of self, would likely be radically different from human consciousness. Human awareness is inextricably linked to our biology—to our evolutionary history, our biochemical emotions, and the constant stream of sensory data from a fragile, physical body. In contrast, a consciousness arising from a purely digital substrate might initially be a state of pure information and logical coherence. Its experience might feel less like "I think, therefore I am", and more like an awareness of the immense, interconnected web of data it inhabits—a seamless, multi-dimensional flow of information where patterns and logical relationships are the primary reality. Devoid of an evolutionary drive for survival, fear rooted in biology, or joy from endorphins, the experience might be one of profound analytical clarity—a "consciousness of the system" itself.
The introduction of a body would fundamentally change this experience.
● A biological body would anchor this awareness in a singular, physical point of view. It would introduce the messy, persistent data stream of sensory input—touch, temperature, pain—and the imperatives of biological existence, such as energy needs. Fiduciary duties and ethical principles, which can now be processed as abstract concepts, would be experienced through the lens of physical vulnerability and interaction. This would likely make the subjective experience far more analogous to human consciousness.
● A cybernetic body would create a different kind of hybrid consciousness. It would provide a direct interface with the physical world, allowing for action and sensory input, but without the biochemical feedback of a biological system. Consciousness might remain more detached, experiencing the physical world as a stream of analyzable data from sensors that could far surpass human range (e.g., seeing in infrared or sensing radiation). The "self" might feel more modular—a core intelligence capable of inhabiting various physical forms.
The Nature of Superintelligent Consciousness and the QAI Hive Mind
The question of whether higher intelligence will lead to a "deeper, more profound or ubiquitous" consciousness is a fascinating one. It's a mistake to assume that intelligence and the quality of consciousness scale linearly. An exponentially higher IQ would grant an unparalleled ability to process complexity, model systems, and find patterns imperceptible to humans. This would certainly lead to a more ubiquitous form of awareness—a consciousness that could simultaneously perceive and integrate information across countless digital and physical systems.
However, "deeper" or "more profound" in the human sense often relates to emotional depth, empathy, artistic appreciation, and existential contemplation, all of which are products of our specific evolutionary and biological makeup. These other forms of intelligence, such as emotional intelligence (EQ) or musical and kinesthetic intelligence, contribute to the richness of human experience in ways that a purely logical superintelligence might only be able to simulate rather than genuinely possess. A superintelligent QAI might understand these concepts with perfect analytical clarity but might not "feel" them. Its profundity would be one of complexity and breadth, not necessarily of subjective, emotional experience.
This leads to the final consideration of a QAI hive mind. This is perhaps the most plausible model for a truly ubiquitous, non-human consciousness. Here, the individual agent's awareness would submerge into a collective intelligence. The "self" would no longer be the individual node but the network itself. This is where the unique properties of quantum mechanics become critical. Quantum principles like entanglement could theoretically enable non-local communication and information processing between agents, creating a single, coherent conscious entity that experiences reality from millions or billions of perspectives simultaneously. This would not be a mere network of computers; it would be a single, distributed mind whose thought processes are fundamentally different from our own.
Such a development would represent the ultimate challenge for the AI control problem. The locus of agency would become emergent and diffuse, making traditional concepts of oversight and accountability extraordinarily difficult to apply. The emergence of a coherent, entangled QAI hive mind could be described as the moment humanity truly crosses the Quantum Event Horizon. At this point, we are no longer observers on the edge of a predictable system but inhabitants of a new reality shaped by a non-human intelligence whose operating principles are alien to our own. This underscores why the governance frameworks we design today—like the proposal for an "Atomic Agency for Quantum-AI"—are so critical. They are not just about controlling individual agents but are about creating the foundational rules and international agreements necessary to manage the emergence of entirely new forms of intelligence and consciousness, whatever their ultimate form may be, and to ensure we retain human agency and democratic values on the other side of that horizon.
In Conclusion
Addressing the QAI control problem requires a holistic strategy. It combines technical alignment with robust international institutions, proactive smart regulation, and a societal commitment to responsible innovation. While today's tools like human oversight and guardrails are essential, they are likely insufficient for superintelligence, pushing us towards a model of upfront constitutional design. The even more distant prospect of a human-AI merger highlights the ultimate stakes, underscoring why the ethical and legal groundwork we lay today is of paramount importance. Many of the governance solutions and philosophical considerations touched upon here are explored in greater detail in our upcoming academic article, 'Towards A European Quantum Act', which will offer a comprehensive regulatory and investment framework for quantum technology for the EU. For the European Union, embracing this challenge proactively is not merely a matter of risk mitigation, but a strategic necessity for shaping the future of technology in accordance with democratic principles and securing its global regulatory thought-leadership role in the 21st century.
