Abstract
Integrated photonics presents an opportunity for low-cost, lightweight and highly-reproducible quantum cryptographic systems. We show that incorporating integrated photonics within pluggable modules a chip-based QKD system operating in real time and with highly competitive secure key rates can be realised with room temperature single photon detectors. The pluggable modules also benefit from their ability to be easily upgraded and replaced so that as the technology matures the system performance can be further enhanced. We also show that our system can be used with standard classical cryptography systems enabling secure data transfer at 100G.
