Single photons for quantum cryptography and medical imaging


The Dutch company Single Quantum recently received a NanoNextNL Valorisation Grant to further develop their technology. Single Quantum has developed equipment to transmit and receive single photons, which allows for applications in the areas of quantum cryptography and medical imaging. The technology consists of a detector chip capable of detecting at least seven in ten passing photons, whereas competing technology can detect only one in ten.

Producing single-photon sources and detectors

At present Single Quantum is the only company in the world that can produce both single-photon sources and detectors. CEO Sander Dorenbos: ‘We will focus on clients to whom we can sell complete systems, which could for example be used to do quantum cryptography experiments.’ Read the entire interview with Sander Dorenbos in the NanoNextNL highlight Transmitting and receiving single photons.
