Definition
Decoherence can be viewed as the loss of information from a system into the environment (often modeled as a heat bath), since every system is loosely coupled with the energetic state of its surroundings.
Context
In quantum mechanics, we appeal to Decoherence as a process that explains the emergence of a quasi-classical order. Decoherence has no classical counterpart. Moreover, it is an apparently irreversible process. Decoherence and quantum entanglement are two physical phenomena that tend to go together. The former relies on the latter, but the reverse is not true. See the wiki page on "Entropy Problems" for a discussion of the boundary conditions that determine the flow of time and whether Decoherence of an Entangled State has a foundational roles in the origin of time.
