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...
