During this time, he made significant contributions to the development of solid-state quantum devices, including single photon and entangled photon sources based on shaped nanowire heterostructures, as well as nanowire-based single electron devices and efficient nanowire avalanche photodiodes. In 2013, Dr. Reimer also played a key role in the startup company Single Quantum, which focused on developing highly efficient single-photon detectors using superconducting nanowires.
