Quantum-Enhanced Multi-Phase Distributed Sensing with a tSU(1,1) Interferometer
We demonstrate the detection of a linear superposition of two distributed phases with a 1.7 dB quantum noise reduction using a tSU(1,1) interferometer. We extend the system theoretically to a multi-phase distributed sensing scheme.
