The measurement problem for the optical phase has been traditionally attacked for noiseless schemes or in the presence of amplitude or detection noise. In this presentation we address, both theoretically and experimentally, the estimation of a a phase shift in the presence of phase diffusion and, in particular, of large phase diffusion. We present a nearly optimal interferometric scheme based...

Since the 1935 proposal by Einstein Podolsky and Rosen the riddle of quantum nonlocality, today demonstrated by innumerable experiments, has been a cause of concern and confusion within the debate over the foundations of quantum mechanics. The talk tackles the problem by a non relativistic approach based on the Weyl's conformal differential geometry applied to the Hamilton-Jacobi solution of...

We present non-Markovian quantum jump description of open system dynamics and discuss how this describes quantum memory effects. Furthermore, we show how to quantify non-Markovianity of open system with a trace distance based measure and information flow concluding with some experimental applications.

Semi-classical approximations to quantum theory describe part of the system classically and part quantum mechanically. In the usual approach, one considers the classical system to move under a mean force, obtained by averaging over the quantum system. We consider an alternative approach based on de Broglie-Bohm theory. This approach has shown to yield better results than the mean force...
