Quantum System

undefined:

A quantum system is a system that, when not under observation, or experiencing stress, appears to go inactive. Examples may include a system that, while away from people they're out as plural to, will appear to collapse, only having a small roster of fronters or only one, or a system that, when not under stress, will slowly stop switching, before settling in an "unobserved" state.

History
The term comes from quantum mechanics, and the observer effect. Particles, when observed, will always act differently than when they do while under observation, similarly to Quantum Systems. Initial coining is here on Pluralpedia.
