Exact Pointer Properties for Quantum System Projector Measurements with Application to Weak Measurements and Their Accuracy
Exact Pointer Properties Quantum System Projector Measurements Application Measurements Accuracy
2010/11/5
Exact pointer states are obtained for projection operator measurements performed upon pre-selected (PS) and upon pre- and post-selected (PPS) quantum systems. These states are used to provide simple e...
Geometric measure of quantum discord for an arbitrary state of a bipartite quantum system
Geometric measure quantum discord for arbitrary state bipartite quantum system
2010/11/4
Quantum discord, as introduced by Olliver and Zurek [Phys. Rev. Lett. \textbf{88}, 017901 (2001)], is a measure of the discrepancy between quantum versions of two classically equivalent expressions fo...
Dynamical cooling of a single-reservoir open quantum system via optimal control
Dynamical cooling single-reservoir quantum system via optimal control
2010/11/9
Based on an exact description of open quantum systems in terms of stochastic Liouville-von Neumann equations optimal control is investigated without rotating-wave or Markovian approximations. Within t...
On the Spectrum of a Discrete Non-Hermitian Quantum System

2010/4/13
In this paper, we develop spectral analysis of a discrete non-Hermitian quantum system that is a discrete counterpart of some continuous quantum systems on a complex contour. In particular, simple con...
