Open quantum system

From Wikipedia, the free encyclopedia

In physics, an open quantum system is a quantum system which is found to be in interaction with an external quantum system, the environment. The open quantum system can be viewed as a distinguished part of a larger closed quantum system, the other part being the environment.

Open quantum systems are an important concept in quantum optics, Measurement in quantum mechanics, quantum statistical mechanics, quantum cosmology and semiclassical approximations.
