Atom Lasers, Coherent States, and Coherence:II. Maximally Robust Ensembles of Pure States

H. M. Wiseman, John A. Vaccaro

As discussed in Wiseman and Vaccaro [quant-ph/9906125], the stationary state of an optical or atom laser far above threshold is a mixture of coherent field states with random phase…

Inequivalence of pure state ensembles for open quantum systems: the preferred ensembles are those that are physically realizable

H. M. Wiseman, John A. Vaccaro

An open quantum system in steady state $ρ^_{ss}$ can be represented by a weighted ensemble of pure states $ρ^_{ss} = \sum_{k} ℘_{k} ∣ ψ_{k} ⟩ ⟨ ψ_{k} ∣$ in infinitely many ways…
