Quantum N.O.D.E (Network Operational Device rEceiver)

This project seeks to establish the foundations for developing a quantum NODE (Quantum Network Operational Device rEceiver) Architecture, using silicon-based waveguide circuits with integrated superconducting nanowire single photon detectors (SNSPDs). This new node-based network architecture will dramatically reduce the resources required for secure quantum communication networks, relieving the users from the need to have bulky and costly high performing detectors, and concentrating these expensive resources into a single central location. Integrated photonics approaches will be utilised to significantly reduce the technology footprint, whilst simultaneously enabling scaling. The proposal builds on a highly successful existing collaboration between the University of Bristol and the University of Glasgow, expanding their joint activity on integrated quantum photonics for quantum computing supported by an EPSRC programme grant. BT will provide their networking expertise to deploy a NODE network demonstration at Adastral Park – proving a compelling quantum NODE demonstrator for the Quantum Communications Hub. Proof-of-principle prototypes of this NODE concept will be demonstrated, targeting fully integrated NODE devices suitable for scaling up to support many users in later development stages.
