In this video I use a type II superconductor to perform a quantum locking demonstration using YCBO (Yttrium barium copper oxide). I then explain in depth how superconductors and quantum locking (Flux ...

In a paper published today in Nature Communications, researchers from the Paul Drude Institute in Berlin, Germany, and the Instituto Balseiro, Bariloche, Argentina, demonstrated that light emitters ...

A series of demonstrations considerably ease the requirements for implementing quantum cryptography protocols over large distances. QKD—arguably the most mature among quantum technologies—works by ...
