We develop interferometry-based atomic inertial sensors robust to Doppler-type inhomogeneities by using quantum optimal control methods. Theoretical results show optimized phase profiles of Raman and Bragg optical π-pulses enabling maximization of the fidelity.

We observe the efficient coupling of free electrons to the optical mode of a chip-integrated high-Q Si3N4 microresonator. This enables strong stimulated inelastic scattering for continuous optical pumping and photon generation for an empty cavity.

We show an optical heterodyne spectrometer with picometer resolution and high sensitivity. Moreover, we report the quantum limit of detecting multi-mode light using heterodyne detection, and compare it to a typical down conversion source output.

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.

Efficient and reliable measurement of photonic indistinguishability is crucial for any claim of a quantum advantage in photonics. Using an integrated photonic processor, we introduce and demonstrate a semi-device-independent witness of photonic indistinguishability.
