词源

First attested 1902 (OED) in the electrical engineering sense "the resetting of a coherer." From decohere (also 1902) + -ence, representing the verbal noun (compare decohesion, decoherency). The quantum mechanics concept was introduced in 1970 by German physicist H. Dieter Zeh, writing in the journal Foundations of Physics.
