How Does Noise Affect a Quantum State?



Noise is usually registered indirectly as decay of correlation. Quantum mechanics has a unique form of correlation labelled entanglement. Recent research has focused on the question whether entanglement is subject to a unique form of noise-induced decorrelation. The answer has been found to be positive and the consequences are currently being explored.
