Our recent paper in Physical Review Applied demonstrates a new quantum random number generator which is simple to implement and achieves high bit rates, yet requires almost no trust in the devices used, leading to strongly improved security.

Our paper demonstrating the violation of an Einstein-Podolsky-Rosen steering inequality developed for single-photon path entanglement with displacement-based detection has been published in Physical Review Letters. We use a high-rate source of heralded single-photon path-entangled states, combined with high-efficiency superconducting-based detectors, in a scheme that is free of any post-selection and thus immune to the detection loophole. This result conclusively demonstrates single-photon…

Our paper on the high-speed - 1.25Gbps - generation of quantum random numbers is out in the Journal of Lightwave Technology. The entropy source is based on an amplified spontaneous emission from an erbium-doped fibre, which is directly acquired using a standard small form-factor pluggable module. The module connects to the field programmable gate array (FPGA) of a QKD system. A real-time randomness extractor is implemented in the FPGA, and achieves a sustained rate of 1.25 Gb/s of provably…
