A team of researchers believe they may have a way to test the hypothesis that human intelligence is the result of entrapment in our brains. Doing so will involve creating connections between the human brain and quantum computers, and trying to measure changes in memory.
The mind is something we all have, but know little about. We know how to turn it off with anesthetics, but we’re not sure how they work. There are many people working on this problem, but we still don’t know if awareness is the result of integration within the system (known as the integrated information hypothesis) or the result of shared information. across the brain (global concept of work), two main ideas. Little is known, there is room for other ideas, many more out there.
In 1989, British mathematician and Nobel Prize winner in Physics, Roger Penrose, did just that, suggesting that quantum entanglement is involved in emotions. Although we cannot summarize his full argument, which is spread over several books, its essence boils down to the idea that there are problems that cannot be solved or understood by traditional computers. Humans can deal with these problems and understand them, such as uncountable numbers and Gödel theorems, so the human mind does not have to work like a traditional computer. Instead, Penrose suggests that consciousness may arise as a result of quantum entanglement within the brain.
The argument, which was not well-established at the time, has actually seen a revival in recent years, although it is still on the fringes of psychological research. One limitation in the theory was that quantum entanglement is weak and breaks easily even at low temperatures, so how can we generate and maintain entanglement in the warm mushy environment of our brains ?
But since then, it has been suggested that the microtubules inside neurons can provide this stable environment for catching. Earlier this year, another group claimed to have found evidence to support this theory, after giving rats microtubule-binding drugs and finding that it now took longer for the anesthesia to wear off. out, suggesting that they played some role in the recovery.
While further research in the area may shed more light on what the mind is and how it works, another group has a surprising idea to test whether the mind is a quantum process. The team, which includes Hartmut Neven, head of Google’s Quantum AI lab, suggests that Penrose was wrong in his suggestion that consciousness arises from superposition collapse, instead suggest that it may appear when it is created, in order to avoid the absurdity. the possibility of faster-than-light communication in the brain.
The team suggests that the way to test this theory of mind is to try to “extend” our knowledge by using the interface between our brain and a quantum computer.
“In the experimentum crucis, a person would establish a physical connection between the human brain and a quantum computer that would create stable connections and interference. than the experiences of the reports of people without a link,” the team explains in their paper, adding that they need to integrate the system in the brain with qubits by superposition. in a quantum computer.
“Before the systems are coupled, their different states exist in separate state spaces, known as Hilbert spaces, of dimensions N and M, respectively. After they are made to interact, the wave function is defines a unified system | “We think that the high level that appears in this high-level space would experience the subject as a richer experience compared to the high level created in the low N-dimensional Hilbert space that describes the isolated brain of matter.”
Speaking to New Scientist, Neven explained how that would work.
“Let’s say we have ‘N’ qubits in our brain and ‘M’ qubits in an external quantum computer, with letters referring to the number of qubits. If one were to enter the brain of home with this quantum computer, he can do extended quantum superposition involving ‘N+M’ qubits,” Neven said. “If we then push this extended superposition to make it fall, then this should be reported by the person participating in this experiment as a rich experience. That is because with their normal experience of knowledge, they often need pieces of ‘N’ to describe the experience, but now they need ‘N+M’ pieces to describe it.”
“I call this the ‘expansion protocol’, as it would allow us to expand knowledge in space, time and complexity.”
According to Neven, accounts of rich experiences in these situations can provide evidence that perception is a phenomenon. Although a good idea, the experiment would depend on being able to connect the human brain to a quantum computer, which is an invasive process and will not happen anytime soon.
Apart from this, there are many other ideas about promise and promise, most of which do not rely on such invasive procedures. As the team notes, research into inert gases like xenon and their impact on science can be very fruitful right now.
