Quantum Light Source for Ultra-Secure Satellite Links: building and testing a CubeSat-ready prototype
We rely on digital locks to keep national and business data safe. Future quantum computers could break today’s encryption. A proven fix is to use pairs of linked light particles (“entangled photons”) to create keys that cannot be copied. Current light sources are big, fragile, power-hungry and costly for affordable CubeSats. We will build and laboratory-test a matchbox-sized source that runs on very low power and fits small satellites. With a North East SME partner we will agree the plug-and-play interface, run a regional workshop and produce a market assessment and follow-on funding plan for the next phase.
