Major advances in chip-based work have been achieved by Hub partners. The QET Labs research group at Bristol achieved the first chip-to-chip QKD, migrated most functionality to silicon photonics, and demonstrated an early WDM capability to increase key rates. Cambridge developed a new integrated network switch architecture (compatible with quantum signals and trusted node or end-to-end operation) and, with York, a novel, combined classical and quantum transmitter based on a CV-QKD design. We are continuing to increase the communication rates of devices while always designing with network compatibility in mind. The Hub is seeking to elevate the level of security assurance and contribute to, adopt, and adhere to new worldwide certification standards for quantum encryption technology. With the increasing activity in companies and ISCF projects towards commercialisation of chip-based technologies, the Phase 2 Hub can put focus on low-TRL investigations of next generation chip applications.
