We have continued the development of several photonic quantum technologies single-photon and entangled-photon sources from quantum dots and parametric down-conversion solid-state quantum gates based on quantum dots in semiconductors and on NV centers in diamond quantum memories using optical storage systems and high-efficiency single-photon detectors, using optimized visible light photon counters, superconducting bolometers, and frequency upconverters to be able to detect telecommunication wavelengths using superior visible-wavelength detectors. For most of these devices, we have already successfully performed experimental demonstrations. We have also continued our work on combining these devices into quantum information systems, by continuing to work on and improve the experimental demonstrations of quantum repeater protocols that we, by working on quantum information systems on chip, and of our high-speed quantum cryptography systems, and also by continuing to work on quantum information encoding into transverse spatial modes.
