We use a loss-tolerant time-multiplexed detector based on a fiber-optical setup and a pair of photon-number-resolving avalanche photodiodes. By capitalizing on an expedient data-pattern tomography, we assess the properties of the light states with outstanding accuracy. The method allows us to reliably infer the squeezing of genuine two-mode states without any phase reference.engjournal articlehttp://dx.doi.org/10.1103/PhysRevLett.116.133601http://journals.aps.orgopen access535Quamtum stateTomographyÓptica (Física)2209.19 Óptica Física
