Quantum cryptography promises an attractive means to secure data transmission on optical networks. However, current systems are expensive, due to their use many discrete fibre optic components and complex control electronics. Furthermore, they have not yet been subject to the same scrutiny as commercial cryptographic products and are known to have potential implementation security issues. This project will address these limitations allowing commercialisation of quantum security devices and systems. It will develop innovative ideas for mass-manufactured, chip-based devices, of greatly reduced size and cost, for high rate quantum random number generation and quantum key distribution, based on manipulating the optical phase in laser diodes. These devices, along with quantum resistant algorithms, will be embedded into secure communication demonstrators and subject to comprehensive verification of their quantum and classical security. The project will deliver compact, practical prototypes for multi-Gb/s random number generation, low cost quantum key distribution and high bandwidth, low latency data encryption, demonstrate these prototypes to potential customers, and explore the market for quantum security technologies.
