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…
Quantum decoherence and classical correlations of the harmonic oscillator in the Lindblad theory
A. Isar, W. Scheid
In the framework of the Lindblad theory for open quantum systems we determine the degree of quantum decoherence and classical correlations of a harmonic oscillator interacting with…

Uncertainty functions of the open quantum harmonic oscillator in the Lindblad theory
A. Isar, W. Scheid
In the framework of the Lindblad theory for open quantum systems, we derive closed analytical expressions of the Heisenberg and Schrödinger generalized uncertainty functions for a…
