Abstract Current quantum key distribution (QKD) networks focus almost exclusively on transporting secret keys at the highest possible rate. Consequently, they are built as mostly fixed, ad hoc, logically, and physically isolated infrastructures desig

Quantum key distribution (QKD) allows secret key exchange between two users with unconditional security. For QKD to be widely deployed, low cost and compactness are crucial requirements alongside high performance. Currently, the majority of QKD syste

Abstract Measurement-device-independent quantum key distribution (MDI-QKD) is a technique for quantum-secured communication that eliminates all detector side-channels, although is currently limited by implementation complexity and low secure key rate

The mid-infrared (mid-IR) spectral region holds great promise for new laser-based sensing technologies, based on measuring strong mid-IR molecular absorption features. Practical applications have been limited to date, however, by current low-brightne

Mode-locked fiber laser technology to date has been limited to sub-3 μm wavelengths despite significant application-driven demand for compact picosecond and femtosecond pulse sources at longer wavelengths. Erbium-doped and holmium-doped fluoride fib

We propose and implement a software-defined network architecture that integrates the QKD SDN Controller within the QKD node, enabling it to use quantum keys to secure its communication with SDN agents while optimizing QKD-keys consumption.

We demonstrate a simplified optical transmitter design for generating intensity-and phase-modulated pulses, using injection locking and pulse interference. The transmitter is applied for proof-of-principle quantum key distribution, achieving Mbps sec

We demonstrate a self-tuning QKD transmitter by employing a genetic algorithm for automated optimisation. Without user intervention, laser parameters are determined automatically to minimise quantum bit error rates to similar levels achieved by QKD s

Mid-infrared (mid-IR) fiber lasers that are based on dysprosium (Dy) as the active laser ion provide emission in the wavelength range between 2.6–3.4 μm and can thus bridge the spectral gap between holmium (Ho) and erbium (Er) based mid-IR lasers.
