Experimental Demonstration of Multi-Parameter Estimation at the Ultimate Quantum Limit (QW6A.17)

Presenter: Benjamin Brecht, Paderborn University

We demonstrate the quantum-limited simultaneous estimation of the timing centroid, offset, and intensity imbalance of an incoherent mixture of two single-photon level pulses. Our measurement saturates the quantum Cramér-Rao lower bound.
