Abstract

It is well know that the quantum state of a single-mode radiation field can be reconstructed by optical tomography based on balanced homodyne four-port detection.1 Moreover, the measured distributions can be related to the density matrix in a field strength basis by a two-fold Fourier transformation.2 To reconstruct the quantum state of a correlated two-mode field,3 or even of a correlated N mode field, general methods of multiport homodyning are required.4
