High Speed (100 Gbps) Encrypted Optical Communications System Based on QKD and Optical Code Scrambling

Quantum key exchange will be used to seed optical code scrambling (OCS), in order to provide significantly enhanced security at high speed (>100 Gbps) data rates. The resources and expertise from three groups at Heriot Watt University and University of Bristol will be combined. The High Performance Networks (HPN) group at Bristol are providing the 100 Gbps test-bed, and access to the national dark fibre facility (NDFIS) along with the “Bristol is Open” network facility. Bristol are also providing relevant technical support. HWU are setting up and operating the quantum key distribution system, while they will also implement and set up the OCS sections and carry out the 100 Gbps OC transmission experiments at Bristol facilities.
