Quantum model reduction for continuous-time quantum filters
Tommaso Grigoletto, Clément Pellegrini, Francesco Ticozzi
The use of quantum stochastic models is widespread in dynamical reduction, simulation of open systems, feedback control and adaptive estimation. In many applications only part of t…
A physical noise model for quantum measurements
Faedi Loulidi, Ion Nechita, Clément Pellegrini
In this paper we introduce a novel noise model for quantum measurements motivated by an indirect measurement scheme with faulty preparation. Averaging over random dynamics governin…
The Asymmetric Quantum Cloning Region
Ion Nechita, Clément Pellegrini, Denis Rochette
Quantum cloning is a fundamental protocol of quantum information theory. Perfect universal quantum cloning is prohibited by the laws of quantum mechanics, only imperfect copies bei…
Parameter Estimation for Quantum Trajectories: Convergence Result
Maël Bompais, Nina H. Amini, Clément Pellegrini
A quantum trajectory describes the evolution of a quantum system undergoing indirect measurement. In the discrete-time setting, the state of the system is updated by applying Kraus…
A geometrical description of the universal asymmetric quantum cloning region
Ion Nechita, Clément Pellegrini, Denis Rochette
We consider the problem of determining the achievable region of parameters for universal asymmetric quantum cloning. Measuring the cloning performance with the figure of…
On stability of quantum trajectories and their Cesaro mean
Nina H. Amini, Maël Bompais, Clément Pellegrini
We address the question of stability of quantum trajectories, also referred as quantum filters}. We determine the limit of the quantum fidelity between the true quantum trajectory…
