Physicists at RIKEN have developed an electronic device that hosts unusual states of matter, which could one day be useful for quantum computation.

When a material exists as an ultrathin layer—a mere one or a few atoms thick—it has totally different properties from thicker samples of the same material. That’s because confining electrons to a 2D plane gives rise to exotic states...

Our Brains use Quantum Computation

Scientists from Trinity believe our brains could use quantum computation after adapting an idea developed to prove the existence of quantum gravity to explore the human brain and its workings. The discovery may shed light on consciousness, the workings of which remain scientifically difficult to understand and explain. Quantum brain processes could also explain why we can still outperform supercomputers when it comes to unforeseen circumstances, decision-making, or learning something new.

The brain functions measured were also correlated to short-term memory performance and conscious awareness, suggesting quantum processes are also part of cognitive and conscious brain functions.

If the team’s results can be confirmed – likely requiring advanced multidisciplinary approaches -the...
