Entanglement under restricted operations: Analogy to mixed-state entanglement
Stephen D. Bartlett, Andrew C. Doherty, Robert W. Spekkens +1
We show that the classification of bi-partite pure entangled states when local quantum operations are restricted yields a structure that is analogous in many respects to that of mi…

Adaptive Quantum Measurements of a Continuously Varying Phase
D. W. Berry, H. M. Wiseman
We analyze the problem of quantum-limited estimation of a stochastically varying phase of a continuous beam (rather than a pulse) of the electromagnetic field. We consider both non…

Atom lasers, coherent states, and coherence: I. physically realizable ensembles of pure states
H. M. Wiseman, John A. Vaccaro
A laser, be it an optical laser or an atom laser, is an open quantum system that produces a coherent beam of bosons. Far above threshold, the stationary state of the laser…
