Engineering fidelity of the generalized Pauli channels via legitimate memory kernels

2019 · Physical Review A

We analyze the fidelity of the generalized Pauli channels governed by memory kernel master equations. It is shown that by appropriate engineering of parameters of the corresponding memory kernel, the quantum evolution with nonlocal noise …

Memory effects displayed in the evolution of continuous variable system

2023 · Physics Letters A

We analyze non-Markovian memory effects displayed by the quantum Brownian motion modelled as a quantum harmonic oscillator coupled to a bath consisting of harmonic oscillators. In particular, the evolution of fidelity, relative entropy and quantum …
