Distributed quantum metrology with a single squeezed-vacuum source
We propose an interferometric scheme for the estimation of a linear combination with non-negative weights of an arbitrary number M>1 of unknown phase delays, distributed across an M-channel linear optical network, with Heisenberg-limited sensitivity. This is achieved without the need of any sources...
