Tomographic measurement of nonclassical radiation states
G. M. D'Ariano, M. F. Sacchi, P. Kumar
We propose to experimentally test the nonclassicality of quantum states through homodyne tomography. For single-mode states we check violations of inequalities involving the photon…

A quantum-mechanical study of optical regenerators based on nonlinear-loop mirrors
Giacomo M. D'Ariano, Prem Kumar
We present a quantum-mechanical analysis of a nonlinear interferometer that achieves optical switching via cross-phase modulation resulting from the Kerr effect. We show how it per…
