TOPIC: Quantum imaging through post-selection

Abstract
In proper quantum metrology protocols a measurement resolution higher than permissible with classical resources is achieved using quantum effects (entanglement/squeezing) to sample the system to be measured. In "filtering" quantum metrology protocols, instead, we only use robust classical resources to sample the system, but we use quantum effects to process them. This implies that filtering protocols will not be able to beat the performance of the optimal classical protocols, but they may be simpler to realize in practice. In this talk I will present one such filtering protocol, to increase the resolution of imaging apparatuses. An experiment in the lab of Franco Wong at MIT will be presented.
