The Quantum Communications Hub has allocated funds (Partnership Resource) to support new collaborations which are closely aligned with the work of the Hub and support new capabilities. Updated deadlines and guidelines on how to submit proposals for consideration will be published soon.
To date, the Hub has made a number of investments in strategic potential: feasibility studies; proofs of concept; preliminary developments; demonstrators.
This project is designed to take advantage of the world leading expertise at Heriot Watt in the technology of ultrafast laser inscription – a laser writing technology that facilitates the fabrication of three-dimensional optical waveguides inside dielectric materials.
Realisation of a MDI-QKD prototype that can operate continuously and with spatial separation of the two communicating parties, tackling challenges such as realisation of high-speed, real-time modulation of indistinguishable pulses from remote locations, and synchronisation of those remote locations.
Continuous Variable Quantum Key Distribution (CV-QKD) has recently seen a revival of interest as a potentially high performance technique for secure key distribution over limited distances.
Realisation of satellite QKD with cube satellites, through exploitation of their lower development, launch costs and rapid development, and culminating in a terrestrial demonstration and engineering model of a CubeSat QKD system and optical ground station ready for full mission capability and in-orbit-demonstration.
Quantum Key Distribution (QKD) is a cryptographic scheme which provides an unrivalled level of data security.
Frequency Down-Conversion to Telecom Wavelengths of On-Demand Indistinguishable Single Photons from a Quantum Dot
This project is aiming to realize the world’s brightest on-demand telecom wavelength source of single photons.
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.
Feasibility study to determine availability of capabilities in both advanced optical technologies and manufacturing processes to develop new optical ground receivers.
In-depth security study of satellite QKD, examining various assumptions about the physical channel between satellites and ground stations and aiming to add new capabilities through maximising the user exploitability of current and future quantum satellite missions.
Development of an atmospheric visibility model, based on high temporal and spatial resolution data used to determine realistic optical transmission statistics derived from short (90 minutes) to medium (1 year) timescale data, and of value to missions currently in planning.
This project seeks to develop the necessary theoretical and experimental understanding, expertise and techniques to test physical quantum random number generators.
The UK Quantum Communications Hub are engaging into a partnership with the National STEM Learning Centre and the University of York Science Education Group to deliver a comprehensive scheme of quantum-related CPD and classroom-based activities.
The project is developing quantum-enabled secure tokens, which can be used on financial and other networks where time is critical and the light speed signalling bound is significant.
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).
The biggest challenge to overcome in long-distance QKD is optical loss. Current mission designs foresee separate optical telescopes, light sources and detectors for the quantum channel and the classical guiding beacon, which strains the stringent size and payload limitations any space mission is subject to.
