Abstract

The aim of quantum sensing is to develop quantum methods to extract the maximum amount of information from a system with minimal disturbance upon it. Indeed, the possibility of performing precision measurements by adopting quantum resources can increase the achievable precision going beyond the semiclassical regime of operation [1,2,3]. However the quantum states suitable for quantum metrology protocols, result extremely fragile under losses and decoherence, unavoidable in experimental implementations, destroying completely quantum benefits [4,5]. This scenario puts the beating of realistic, noisy environments as the main challenge in developing quantum sensing.
