Integrated Quantum Optical Phase Sensor
, 2022 Abstract The quantum noise of light fundamentally limits optical phase sensors. A semiclassical picture attributes this noise to the random arrival time of photons from a coherent light source such as a laser. An engineered source of squeezed states suppresses this noise and allows sensitivity beyond the standard quantum limit (SQL) for phase ...

Improving SPDC single-photon sources via extended heralding and feed-forward control
New Journal of Physics, 2019 Evolving photonic quantum technologies and applications require higher and higher rates of single photon generation. In parallel, it is required that these generated photons are kept spectrally pure for multi-photon experiments and that multi-photon ...
