Efficient Detection of Squeezed Light on Nanophotonic Chips using Subwavelength-Engineered Superconducting Nanowire Avalanche Photodetectors

Project description

Novel photonic integrated systems to efficiently detect squeezed light

Squeezed states of light have quantum correlations that give rise to smaller measurement uncertainties than corresponding classical states. Such quantum features can be exploited for optical high-precision measurements, radiometry, quantum key distribution, etc. Current nanophotonic chips using waveguide-integrated superconducting nanowire single-photon detectors (SNSPDs) are limited in their ability to detect squeezed light mainly owing to the coupling losses of both fibre-chip couplers and waveguide-to-SNSPD interfaces. Funded by the Marie Skłodowska-Curie Actions programme, the ESSENS project will develop a photonic integrated system to efficiently detect squeezed light at telecom wavelengths. The proposed systems will open up exciting uses of squeezed light in applications such as quantum simulation, communication, and sensing with hundreds of detectors and interferometers on highly integrated monolithic chips with near perfect stability.
