How much state assignments can differ
Todd A. Brun, J. Finkelstein, N. David Mermin
We derive necessary and sufficient conditions for a group of density matrices to characterize what different people may know about one and the same physical system.
A simple model of quantum trajectories
Todd A. Brun
Quantum trajectory theory, developed largely in the quantum optics community to describe open quantum systems subjected to continuous monitoring, has applications in many areas of…
Martingale Models for Quantum State Reduction
S. L. Adler, D. C. Brody, T. A. Brun +1
Stochastic models for quantum state reduction give rise to statistical laws that are in most respects in agreement with those of quantum measurement theory. Here we examine the cor…
Generalized stochastic Schroedinger equations for state vector collapse
Stephen L. Adler, Todd A. Brun
A number of authors have proposed stochastic versions of the Schrödinger equation, either as effective evolution equations for open quantum systems or as alternative theories with…
