The Quantum Tomographic Roulette Wheel

G. M. D'Ariano, M. G. A. Paris

Random-phase homodyne tomography of the field intensity is a concrete example of the Quantum Roulette of Helstrom. In this paper we give the explicit POM of such measurement and co…

Optical von Neumann measurement

G. M. D'Ariano, M. F. Sacchi

We present an optical scheme that realizes the standard von Neumann measurement model, providing an indirect measurement of a quadrature of the field with controllable Gaussian sta…

Trace forms for the generalized Wigner functions

G. M. D'Ariano, M. F. Sacchi

We derive simple formulas connecting the generalized Wigner functions for -ordering with the density matrix, and vice-versa. These formulas proved very useful for quantum mechan…
