  • Abstract We address extended systems interacting with classical fluctuating environments and analyze the use of quantum probes to discriminate local noise , described by independent fluctuating fields, from common noise , corresponding to the interaction with a common one. In particular, we consider a bipartite system made of two non-interacting harmonic oscillators and assess discrimination strategies based on homodyne detection, comparing their performances with the ultimate bounds on the… CONTINUE READING
