DESCRIPTION:Weight estimation for optical detection setups\n\nRealistic models of optical detection setups are crucial for numerous quantum information tasks. For instance\, squashing maps allow for more realistic descriptions of the detection setups by accounting for multiphoton detections. To apply squashing maps\, one requires a population estimation of multiphoton subspaces of the input to the detection setup. So far\, there has been no universal method for those subspace estimations for arbitrary detection setups.\n\nWe introduce a generic subspace estimation technique applicable to any passive linear optical setup\, accounting for losses and dark counts. The resulting bounds are relevant for adversarial tasks such as QKD or entanglement verification. Additionally\, this method enables a generic passive detection setup characterization\, providing the necessary measurement POVM for e.g. QKD security proofs.\n\n
