In this episode of the Justin Riddle Podcast, Justin dives into the concept of Knightian Freedom where large enough computational spaces become intractably complex to the point where maybe freewill is possible. The focus of this episode is a paper put out by Hartmut Neven (of Google’s Quantum AI Lab) and colleagues from 2021 entitled “Do robots powered by a quantum processor have the freedom to swerve?” This paper discusses how the exponentially large spaces that quantum computers evolve into are so large that they cannot be represented or simulated on digital computers. The size is so vast that it would take a computer the size of the universe computing for trillions of years to simulate even a few femtoseconds of the quantum computers that are about to be commonplace. Similar to modern AI, we will won’t be able to understand why a quantum computer generated the output that it did and perhaps this is the essential ingredient that leads to freewill. Rampant incomputable complexity is freewill. Second, Hartmut and colleagues propose a simple experiment to reveal whether or not there are additional factors that play into what output is generated by a quantum computer. Assume you run a quantum circuit that generates a perfect uniform distribution between many different possible outputs. Then, you observe that the quantum computer does not behave as if there was a uniform distribution, but instead selects one of those possible outputs more often. This is the ‘preference’ of the quantum computer. Next, you develop a circuit to amplify these deviations from uniformity with the intention of amplifying the probability of entering into that preferred state. Now, we have essentially created a ‘happy circuit’ which embraces the quirky preference of our quantum computer. Finally, you can correlate deviations from this happy state to psychological data in an effort to build up a taxonomy of subjective experiences that the quantum computer can enter into. Finally, you embed the quantum computer with its happy circuit into an artificial neural network such that errors produced by the AI push the quantum computer away from happiness and this unhappiness is fed back into the AI. Now we have created an AI system with quantum feelings! Will this newfound sense of subjectivity enable more effective AI systems or will the AI get bogged down by a spiral of despair and refuse to compute?! All of these questions and more are explored here. Enjoy!

In episode 24 of the Quantum Consciousness series, Justin Riddle discusses why neuroscience is in need of a quantum revolution. This revolution is underway in the field of information technology and low-level biology. Quantum computers are actively being developed and are on the precipice of overcoming the computational power of digital computers. Meanwhile, biology is increasingly acknowledging the role that quantum mechanics plays in various processes, including photosynthesis and magnetic-field perception in birds. But what about neuroscience? Could quantum mechanics contribute to neural function and directly to our conscious experience? There are quite a few reasons why quantum computers align with the human experience: (1) Quantum computer design encourages the creation of a single large system, similar to the creation of single self within a body. (2) The collapse of the wave function in quantum mechanics may provide room for freewill. (3) Non-local influences in quantum mechanics provide novel ways to describe meaning beyond arbitrary associations in a physical world.
While quantum mechanics provides novel solutions to solving the mysteries of consciousness, neuroscience reveals that the strongest correlate to human cognition is low-frequency electrical fluctuations in the brain. After a brief survey of recent research in the neural oscillatory basis of cognition, the potential alignment between neural oscillations and principles of quantum mechanics are discussed. While this connection is currently speculative, computational models of cognition are pointing towards human rationality exhibiting principles of quantum mechanics. There could be a very near future where descriptions of human psychology are quantum mechanical in nature and the parameters of these models relate to neural oscillations in the brain. While the details for how a quantum computer could be implemented in the brain is of critical need, cognitive neuroscience research can move forward utilizing these ideas in the meantime.
