(Phys.org) —A trio of researchers at Tohoku University in Japan, led by Masahiro Hotta, has proposed a new way to teleport energy that allows for doing so over long distances. In their paper published in Physical Review ...
Suggesting that quantum computers might benefit from losing some data, physicists at the National Institute of Standards and Technology (NIST) have entangled—linked the quantum properties of—two ions by leaking judiciously ...
