In quantum physics decoherence refers to the disappearance of quantum entanglement and superposition in the limit where small quantum mechanical systems are coupled to large thermal baths?.

This has been argued to resolve (and has been argued not to resolve) the problem with the interpretation of quantum measurement.


Original discusssion identifying quantum decoherence as interaction with an averaged environment (“bath”):
