Nu Quantum, the quantum photonics company, has raised £2.1 million in Seed funding in a round led by Amadeus Capital Partners. Ahren Innovation Capital, IQ Capital, Cambridge Enterprise and Martlet Capital have also followed-on from the company's pre-Seed investment round last September, with Seraphim Capital joining as a new investor. The funding will go towards a state-of-the-art photonics lab in Cambridge and a major recruitment drive for scientists, product team members and business functions as the company approaches the launch of its first commercial technology demonstration.
