Decoherence
In quantum mechanics, environmental decoherence describes that quantum states of a closed system change in only one measurable state by interaction with the environment.
Explanation
Decoherence can thus be viewed as the loss of information from a system into the environment, since every system is loosely coupled with the energetic state of its surroundings.
HistoryThe decoherence concept was introduced around 1970 by the German physicist Dieter Zeh. |
