Quantum fidelity for Gaussian states describing the evolution of open systems
Aurelian Isar
Using the expression of the fidelity for the most general Gaussian quantum states, the quantum fidelity is studied for the states of a harmonic oscillator interacting with an envir…

Decoherence and asymptotic entanglement in open quantum dynamics
Aurelian Isar
In the framework of the theory of open systems based on completely positive quantum dynamical semigroups, we determine the degree of quantum decoherence of a harmonic oscillator in…
