Physicists in France are the first to watch single photons appear spontaneously, live a brief life, and then vanish into thin air. The experiment is the best realization so far of "quantum ...

They claim their protocol has set a new world record for quantum state preparation and measurement (SPAM). It shows a 13-fold decrease in SPAM errors compared to the current best method, making it ...

Quantum non-demolition (QND) measurements are used to check the state of the cavities without disturbing the quantum state. This allows for the detection of errors without collapsing the quantum ...
