Quantum-enhanced Sensing and Efficient Quantum Computation
Abstract
Project 13-3025 was a supplemental grant to 12-2076, focusing on near-term applications of single-photon detectors. The group installed high-efficiency Transition Edge Sensors from a collaboration with NIST, USA. The team created new methods to characterize and run TES detectors, and combined embedded photon-counting detectors with multiport inteferometers, and used many of the same techniques with nanowire (faster but less efficient) detectors. They demonstrated single-photon preparation efficieny of greater than 60%, and measured the TES system detection efficiencies to be 92-100, with the ability to count photons with accuracy. The system was used to improve quantum boson sampling tests.
