High-Rate Photon Pairs and Sequential Time-Bin Entanglement with Si${}_3$N${}_4$ Ring Microresonators

Abstract

Integrated photonics is increasing in importance for compact, robust, and scalable enabling quantum technologies. This is particularly interesting for developing quantum communication networks, where resources need to be deployed in the field. We exploit photonic chip-based $\mathrm{S}{\mathrm{i}}_3{\mathrm{N}}_4$ ring microresonators for the generation of photon pairs with low-loss, high-noise suppression and coincidence rates of $80\times 10^3$s${}^{-1}$. A simple photonic noise characterisation technique is presented that distinguishes linear and nonlinear contributions that is useful for system design and optimisation. We then demonstrate an all-fibre $750$MHz clock-rate sequential Time-Bin entanglement scheme with raw interference visibilities $>98\%$.
