Entanglement quantification from incomplete measurements: applications using photon-number-resolving weak homodyne detectors

Abstract:

The certificate of success for a number of important quantum information processing protocols, such as entanglement distillation, is based on the difference in the entanglement content of the system quantum states before and after the protocol. In such cases, effective bounds need to be placed on the entanglement of non-local states consistent with statistics obtained from local measurements. In this paper,we study numerically the ability of a hybrid homodyne detector that combines phase sens...
