Quantum computers teleport and store energy harvested from empty space

Energy cannot be created from nothing, but physicists found a way to do the next best thing: extract energy from seemingly empty space, teleport it elsewhere and store it for later use. The researchers successfully tested their protocol using a quantum computer.

The laws of quantum physics reveal that perfectly empty space cannot exist – even places fully devoid of atoms still contain tiny flickers of quantum fields. In 2008, Masahiro Hotta at Tohoku University in Japan proposed that those flickers, together with the …
