Witnessing Quantum Squeezing with Binary Homodyne Detection

Abstract

Homodyne detection [1] is a typical continuous-variable measurement scheme, ubiquitously used in quantum optics and quantum information. A conventional homodyne detector performs a projective measurement onto a quadrature of the electromagnetic field mode, thus yielding a continuously distributed measurement outcome. The outcome distribution is the marginal of the Wigner function of the state. Homodyne detection also forms the basis of heterodyne, or "dual homodyne" detection, which corresponds to measuring the Q function of the state.
