Quantum limit for driven linear non-Markovian open-quantum-systems

open access: yesNew Journal of Physics, 2015
The interplay between non-Markovian dynamics and driving fields in the survival of entanglement between two non-degenerate oscillators is considered here.

Degradation and Protection of Entanglement in Open Quantum Systems

open access: yesProceedings, 2019
The distribution of entangled quantum systems among the nodes of a network is a key task at the basis of the development of quantum technologies, e.g., quantum communication, quantum computation, etc. Many efforts have been devoted to identify strategies,

Hidden Quantum Memory: Is Memory There When Somebody Looks? [PDF]

open access: yesQuantum, 2023
In classical physics, memoryless dynamics and Markovian statistics are one and the same. This is not true for quantum dynamics, first and foremost because quantum measurements are invasive.

Spins in quantum dots : hyperfine interaction, transport, and coherent control [PDF]

open access: yes, 2008
This thesis deals with several topics related to spin dynamics and transport of electrons in quantum dots. We begin with an introduction in Chapter 1, where we review several important aspects of quantum dots and the microscopic Hamiltonians governing

Non-Markovian dynamics with fermions [PDF]

open access: yesPhysical Review A, 2014
Employing the quadratic fermionic Hamiltonians for the collective and internal subsystems with a linear coupling, we studied the role of fermionic statistics on the dynamics of the collective motion. The transport coefficients are discussed as well as the associated fluctuation-dissipation relation. Due to different nature of the particles, the path to

Qubit entanglement generation by Gaussian non-Markovian dynamics [PDF]

open access: yes, 2019
We consider two qubits interacting with a common bosonic bath, but not directly between themselves. We derive the (bipartite) entanglement generation conditions for Gaussian non-Markovian dynamical maps and show that they are similar as in the Markovian ...
