As with much quantum computing research, the study looks at the idea of entanglement – two separate particles being in states that are linked together"We adapted an idea, developed for experiments to prove the existence of quantum gravity, whereby you take known quantum systems, which interact with an unknown system," says physicist Christian Kerskens from the University of Dublin.In other words, the entanglement or relationship between the known systems can only happen if the mediating system in the middle – the unknown system – operates on a quantum level, too.Through this technique, the researchers were able to see signals resembling heartbeat-evoked potentials, which are a type of electroencephalography (EEG) signal.The observations recorded by the team require verification via confirmation via future studies across multiple scientific fields, but the early results look promising for non-classical, quantum happenings in the human brain when it's active."Our experiments, performed only 50 meters away from the lecture theatre where Schrödinger presented his famous thoughts about life, may shed light on the mysteries of biology, and on consciousness which scientifically is even harder to grasp," says Kerskens."
