On partially entanglement breaking channels
Dariusz Chruscinski, Andrzej Kossakowski
Using well known duality between quantum maps and states of composite systems we introduce the notion of Schmidt number of a quantum channel. It enables one to define classes of qu…
Quantum damped oscillator II: Bateman's Hamiltonian vs. 2D Parabolic Potential Barrier
Dariusz Chruscinski
We show that quantum Bateman's system which arises in the quantization of a damped harmonic oscillator is equivalent to a quantum problem with 2D parabolic potential barrier known…
Quantum damped oscillator I: dissipation and resonances
Dariusz Chruscinski, Jacek Jurkowski
Quantization of a damped harmonic oscillator leads to so called Bateman's dual system. The corresponding Bateman's Hamiltonian, being a self-adjoint operator, displays the discrete…
Wigner function and Schroedinger equation in phase space representation
Dariusz Chruscinski, Krzysztof Mlodawski
We discuss a family of quasi-distributions (s-ordered Wigner functions of Agarwal and Wolf) and its connection to the so called phase space representation of the Schroedinger equat…
