Time Asymmetry in Quantum Physics - II. Experimental Demonstration Using a Single Ion
arXiv:quant-ph/0703163
Abstract
Quantum physics involves an ensemble of quantum systems, usually one thinks of a large ensemble of identical quantum systems at one single time. In single ion experiments one has a single quantum system at an ensemble of different times. This provides the means of demonstrating the beginning of time of a semigroup evolution for a decaying state.
