Ratcheting up energy by means of measurement
L. S. Schulman, B. Gaveau
The destruction of quantum coherence can pump energy into a system. For our examples this is paradoxical since the destroyed correlations are ordinarily considered negligible. Math…
Decay of discrete state resonantly coupled to a continuum of finite width
E. Kogan
A simple quantum mechanical model consisting of a discrete level resonantly coupled to a continuum of finite width, where the coupling can be varied from perturbative to strong (Fa…
Evaluable multipartite entanglement measures: are multipartite concurrences entanglement monotones?
Rafal Demkowicz-Dobrzanski, Andreas Buchleitner, Marek Kus +1
We discuss the monotonicity under local operations and classical communication (LOCC) of systematically constructed quantities aiming at quantification of entanglement properties o…
Dynamics of Loschmidt echoes and fidelity decay
Thomas Gorin, Tomaz Prosen, Thomas H. Seligman +1
Fidelity serves as a benchmark for the relieability in quantum information processes, and has recently atracted much interest as a measure of the susceptibility of dynamics to pert…
An observable entanglement measure for unknown mixed quantum states
Florian Mintert, Andreas Buchleitner
We show how an unknown mixed quantum state's entanglement can be quantified by a suitable, local parity measurement on its two-fold copy.
Phase rigidity and avoided level crossings in the complex energy plane
E. N. Bulgakov, I. Rotter, A. F. Sadreev
We consider the effective Hamiltonian of an open quantum system, its biorthogonal eigenfunctions and define the value that characterizes the phase…
