Shocking Experiment Shows Our Brain Uses Quantum Computing
Scientists believe our brains could use quantum computing after taking a concept developed to prove the existence of quantum gravity and adapting it to explore the human brain and how it works. The discovery could shed light on consciousness, the functioning of which remains scientifically difficult to understand and explain. Quantum brain processes could also explain why humans can still outperform supercomputers when it comes to unforeseen circumstances, decision-making, or learning something new.
After adapting an idea developed to prove the existence of quantum gravity to explore the human brain and how it works, researchers at Trinity College Dublin think the human brain could use quantum computing.
The brain functions measured in the experiment were also correlated with short-term memory performance and consciousness. This suggests that quantum processes are also part of the cognitive and conscious functions of the brain.
“If entanglement is the only possible explanation here, that would mean that brain processes must have interacted with nuclear spins, mediating entanglement between nuclear spins. Accordingly, we can infer that these brain functions must be quantum. — Dr. Christian Kerskens
If the team’s findings could be corroborated, which would likely require advanced multidisciplinary approaches, they would improve our general understanding of brain function. The information could potentially reveal how the brain can be maintained or even healed. They can also help discover innovative technologies and build even more advanced quantum computers.
Dr. Christian Kerskens is the co-author of the research article published October 7 in the Physical Communications Journal. He is also a senior physicist at the Trinity College Institute of Neuroscience (TCIN). He stated :
“We adapted an idea, developed for experiments to prove the existence of quantum gravity, where you take known quantum systems, which interact with an unknown system. If the known systems intertwine, then the unknown must also be a quantum system. It bypasses the difficulties of finding measuring devices for something we know nothing about.
“For our experiments, we used proton spins from ‘brain water’ as a known system. “Brain water” naturally accumulates as liquid in our brains and proton spins can be measured using MRI (magnetic resonance imaging). Then, using a specific MRI design to look for entangled spins, we found MRI signals that resemble heartbeat-evoked potentials, a form of EEG signals. EEGs measure electrical currents in the brain, which some people can recognize from personal experience or simply by watching hospital dramas on television.
Electrophysiological potentials like potentials evoked by heartbeats are not normally detectable by MRI and the scientists believe they could only observe them because the nuclear spins of protons in the brain were entangled.
Dr Kerskens added:
“If entanglement is the only possible explanation here, that would mean that brain processes must have interacted with nuclear spins, mediating entanglement between nuclear spins. Therefore, we can infer that these brain functions must be quantum.
“Because these brain functions were also correlated with short-term memory performance and conscious awareness, it is likely that these quantum processes are an important part of our cognitive and conscious brain functions.
“Quantum brain processes could explain why we can still outperform supercomputers when it comes to unforeseen circumstances, making decisions or learning something new. Our experiments performed just 50 meters from the amphitheater, where Schrödinger presented his famous reflections on life, which can shed light on the mysteries of biology, and on consciousness which is scientifically even more difficult to apprehend.
