A Quantum Field Theory View of Interaction Free Measurements
Filipe Barroso, Orfeu Bertolami
We propose a Quantum Field Theory description of beams on a Mach-Zehnder Interferometer and apply the method to describe Interaction Free Measurements (IFMs), concluding that there…

Phase-space continuity equations for quantum decoherence, purity, von Neumann and Rényi entropies
Alex E. Bernardini, Orfeu Bertolami
Phase-space features of the Wigner flow are examined so to provide a set of continuity equations that describe the flux of quantum information in the phase-space. The reported resu…
