Non-Markovianity and coherence of a moving qubit inside a leaky cavity
Ali Mortezapour, Mahdi Ahmadi Borji, DaeKil Park +1
Non-Markovian features of a system evolution, stemming from memory effects, may be utilized to transfer, storage, and revive basic quantum properties of the system states. It is we…
Protecting entanglement by adjusting the velocities of moving qubits inside non-Markovian environments
Ali Mortezapour, Mahdi Ahmadi Borji, Rosario Lo Franco
Efficient entanglement preservation in open quantum systems is a crucial scope towards a reliable exploitation of quantum resources. We address this issue by studying how two-qubit…
