This is something that repeatedly pops up every time someone goes on a rant against science not doing what they want science to do:
SCIENCE ONLY STUDIES NATURE!
Of course science studies nature. It's what science does.
But if you want science to study the supernatural, that which is supposed to exist beyond and outside nature, you have to actually give it something to work with.
So I ask you: how exactly CAN science study the supernatural? What methods, what tests?

Can we use quantum computers to test a radical consciousness theory?
Hartmut Neven, who leads Google's Quantum AI lab, wants to entangle our brains with quantum processors to test the idea that consciousness involves quantum phenomena

The suggestion that
consciousness has its origins in
quantum weirdness has long been viewed as a bit, well, weird. Critics argue that ideas of
quantum consciousness, the most famous of which posits that moments of experience arise as quantum superpositions in the brain collapse, do little more than merge one mystery with another. Besides, where is the evidence? And yet there is a vocal minority who insist we should take the idea seriously.
Hartmut Neven, who leads
Google’s Quantum Artificial Intelligence Lab, is among them. He originally trained as a physicist and computational neuroscientist before pioneering computer vision – a type of
AI that replicates the human ability to understand visual data. Later, Neven founded Google Quantum AI, which in 2019 became the first lab to claim its quantum computers solved calculations that are impossible on a classical computer, a milestone known as
quantum supremacy. In December 2024, his team announced another step forward with its new quantum processor, Willow, which it claims is more powerful and reliable than previous chips.
Nerve fibres in the brain could generate quantum entanglement
Calculations show that nerve fibres in the brain could emit pairs of entangled particles, and this quantum phenomenon might explain how different parts of the brain work together
But Neven is also interested in the relationship between mind and matter. And now, in a use case for quantum computers that no one saw coming, he reckons they could be deployed to put the idea of quantum consciousness to the test. Neven spoke to
New Scientist about his belief that we live in a multiverse; why Roger Penrose’s theory of quantum consciousness is worth pursuing, albeit possibly with a new twist; and how we can test such ideas by entangling quantum computers with human brains.
Thomas Lewton: How has working at the forefront of quantum computing altered your view of what reality is?
Hartmut Neven: We recently ran a computation on our new quantum processor, named Willow, that would take the best classical supercomputer an astounding amount of time to complete: 1025 years. This mind-boggling number exceeds known timescales in physics and vastly exceeds the age of the universe. To me, this result suggests that quantum processors are tapping into something larger than just our universe, lending credence to the notion that their computation occurs in many parallel universes.
Over the years, I’ve come to appreciate that the most straightforward reading of the equations of quantum mechanics is that, indeed, we live in a multiverse: that every object, including myself or the cosmos at large, exists in many configurations simultaneously. This view of reality has profoundly shaped my everyday outlook on life.
In what way?
My general stance when describing the world is physicalism, which states that every phenomenon we witness can be explained as a manifestation of matter. But the only phenomenon that we are certain exists is conscious experience. Everything starts from experience; without mind, nothing matters.
So then the task you have as a physicalist is to identify the locus of consciousness. Here, I think, quantum mechanics has a unique advantage over classical mechanics – and it is directly related to the
multiverse picture.
If the multiverse picture is correct, then there are a vast number of parallel worlds. But right now, you and I coexist in a definite, classical branch of the multiverse. So why do we witness this configuration and not the other ones? This is an opportunity to place consciousness in your physicalist theory. An attractive conjecture is that consciousness is how we experience the emergence of a unique classical reality out of the many that quantum physics tells us there are.
Consciousness seems like a very different kettle of fish to quantum physics. How can one be accommodated into the other?
I’m a disciple of Roger Penrose, who, in his 1989 book
The Emperor’s New Mind, put forth the idea that
consciousness involves a state of matter in quantum superposition, where a quantum object exists in multiple configurations at the same time. When the superposition collapses during a “measurement” process, one classical branch gets selected out of many possible branches and this implements a conscious moment. I always thought this was beautiful because then qualia – specific subjective experiences such as the redness of a rose or the feelings that music evokes – can naturally be encoded into the state that [the superposition] collapses into.
