Entanglement of Bipartite Quantum Systems driven by Repeated Interactions
S. Attal, J. Deschamps, C. Pellegrini
We consider a non-interacting bipartite quantum system undergoing repeated quantum interactions with an environment modeled by a chain of inde…
Stability of continuous-time quantum filters with measurement imperfections
Hadis Amini, Clement Pellegrini, Pierre Rouchon
The fidelity between the state of a continuously observed quantum system and the state of its associated quantum filter, is shown to be always a submartingale. The observed system…
Complex Obtuse Random Walks and their Continuous-Time Limits
S. Attal, J. Deschamps, C. Pellegrini
We study a particular class of complex-valued random variables and their associated random walks: the complex obtuse random variables. They are the generalization to the complex ca…
Large Time Behaviour and Convergence Rate for Non Demolition Quantum Trajectories
Tristan Benoist, Clement Pellegrini
A quantum system S undergoing continuous time measurement is usually described by a jump-diffusion stochastic differential equation. Such an equation is called a stochastic master…
A universal set of qubit quantum channels
Daniel Braun, Olivier Giraud, Ion Nechita +2
We investigate the set of quantum channels acting on a single qubit. We provide an alternative, compact generalization of the Fujiwara-Algoet conditions for complete positivity to…
