Introduction to Single Photonics and Quantum Radiometry Short Course:
Sources, Detectors and Measurements
February 21–24, 2023
Boulder, Colorado
In cooperation with researchers and metrologists from around the world, the University of Colorado Boulder will present a short course consisting of lectures and hands-on lab interaction. Demonstrations and labs will be provided by industrial partners active in the field.

Sponsored by: NIST, Quantum Opus, Qubitekk, S15 Instruments, Colorado Photonics Industry Association and ThorLabs

Who should attend
- Technologists looking for an introduction to a new field and networking
- Experienced engineers or technicians in a related field looking for an introduction
- Researchers seeking a better understanding of and expressing measurement results
Topics
- Detectors
- PMTs, SPADs, SNSPDs, TESs (if you don’t know the acronyms, come to the course!), how do we define detection efficiency? What is detector tomography?
- Sources
- Down conversion, quantum dots, nitrogen vacancies, What’s the difference between a single photon source and simply ‘faint light’?
- Measurements and use cases
- Detection efficiency, photon number, dark counts, jitter, dark counts. What is ‘spooky action at a distance’? What does a calibration report tell me?
- Engineering
- Cryogenics, optics, optical fibers and optimization, statistics and uncertainty
