We use a sensitivity measure based on the method of moments and compare direct imaging with spatial-mode demultiplexing (SPADE), analytically proving advantage of the latter. We show that the moment-based sensitivity of SPADE saturates the quantum Fisher information for all known cases, even for non-Gaussian states of the sources.", optnote="WOS:000876858200004", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=5400), last updated on Sat, 12 Nov 2022 20:19:37 +0000", doi="10.1103/PhysRevResearch.4.043010", opturl="https://doi.org/10.1103/PhysRevResearch.4.043010", language="English" }
