Efficient characterization of N-beam Gaussian fields through photon-number measurements: Quantum universal invariants
Quantum universal invariants of general N-beam Gaussian fields are investigated from the point of view of fields' intensity moments. A method that uniquely links these invariants, including the global and marginal fields' purities, to intensity moments is suggested. Determination of these...
