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…
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…
Markovian master equations for quantum-classical hybrid systems
Alberto Barchielli
The problem of constructing a consistent quantum-classical hybrid dynamics is afforded in the case of a quantum component in a separable Hilbert space and a continuous, finite-dime…
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…
The eight-port homodyne detector: the effect of imperfections on quantum random number generation and on detection of quadratures
Alberto Barchielli, Alberto Santamato
The eight-port homodyne detector is an optical circuit designed to perform the monitoring of two quadratures of an optical field, the signal. By using quantum Bose fields and quant…
Quantum optomechanical system in a Mach-Zehnder interferometer
Alberto Barchielli, Matteo Gregoratti
We consider an oscillating micromirror replacing one of the two fixed mirrors of a Mach-Zehnder interferometer. In this ideal optical set-up the quantum oscillator is subjected to…
