Conjugate measurements, equilibration and emergent classicality

Quantum Physics [Submitted on 27 Mar 2026] Conjugate measurements, equilibration and emergent classicality S. Adarsh, P.N. Bala Subramanian, Sreeraj T. P Simultaneous decoherence of conjugate observables of an open quantum system leads to a classical statistical mechanical description with constant phase space probability density in terms of a uniform ensemble. We investigate a scenario where this may be realized by measurement of basic conjugate observables of a quantum system by the environment.
