Interferometry at the Fundamental Quantum Limit Using Squeezed Light
We detail the achievement of the fundamental quantum interferometry limit. We present the theory of such a scheme and demonstrate it experimentally with phase- locked squeezed light, double homodyne readout, and the optimal phase estimator.
