decoherence

In quantum physics, this term describes the transition from a quantum state to a classical state. It is not a disappearance of information, but rather the leakage of that information into the surrounding environment, which destroys the interference patterns necessary for quantum computation.

When used metaphorically in social or political contexts, it suggests a systemic fragmentation. It implies a loss of synchronization or a breakdown of a previously unified structure, often conveying a sense of inevitable decay or instability rather than a sudden, violent rupture.
