New research is paving the way for more efficient quantum information transfer. Researchers from Shanghai Jiao Tong ...

As waves travel, they set up patterns of disturbance. The amplitude of a wave is its maximum disturbance from rest (its undisturbed position). Key fact It is important to note that the amplitude ...
