Quantum jump trajectories, hybrid systems, non-Hermitian evolutions, quantum/classical walks
Alberto Barchielli
Quantum stochastic master equations of jump type are formulated in a general way and connections with quantum/classical hybrid systems and quantum filtering theory are discussed. B…

Hybrid quantum-classical systems: Quasi-free Markovian dynamics
Alberto Barchielli, Reinhard Werner
In the case of a quantum-classical hybrid system with a finite number of degrees of freedom, the problem of characterizing the most general dynamical semigroup is solved, under the…

Markovian dynamics for a quantum/classical system and quantum trajectories
Alberto Barchielli
Quantum trajectory techniques have been used in the theory of open systems as a starting point for numerical computations and to describe the monitoring of a quantum system in cont…
