Title: NIST Develops Quantum Radiometry Standards for Single Photon Detection
1. Summary:
The National Institute of Standards and Technology (NIST) is developing quantum radiometry standards to support the emerging quantum industry. The project focuses on measuring and calibrating single photon sources and detectors, which are crucial for quantum applications.
2. Key Points:
– NIST is developing a portable system to calibrate the detection efficiency of superconducting nanowire single photon detectors
– The project explores the metrology challenges associated with precision measurement of single photon sources and detectors
– Classical photonic radiometry techniques can determine absolute detector and source efficiencies down to femtowatt power levels
– Detector calibrations for superconducting and single photon avalanche detectors have been demonstrated and are being developed into commercial services
– Future research directions include integrating true single photon sources, photon number resolving detectors, and waveguide integrated detectors and sources
3. Impact:
– Enables precise calibration of single photon detectors used in quantum technologies
– Supports development of quantum photonic devices and applications
