Quantum Inspired RF Phase Measurement by Parity Estimation
Super-resolved interferometric phase measurements in the RF domain have been demonstrated by estimating the Parity operator through quadrature measurements, saturating the information theoretic Cramer-Rao bound. We achieved 600-fold improvement over the Rayleigh limit with 56dB SNR.
