Distributed Quantum Sensing with Squeezed-Vacuum Light in a Configurable Network of Mach-Zehnder Interferometers

Marco Malitesta, Augusto Smerzi, Luca Pezzè

We study a sensor network of distributed Mach-Zehnder interferometers (MZIs) for the parallel (simultaneous) estimation of an arbitrary number $d\ge 1$ of phase shifts. The schem…
