Metric Week 2023: Seven Days of SI Fun

National Metric Week (October 8 to 14, 2023) is an opportunity to underscore the usefulness of metric system measurements, formally known as the International
NIST chip containing a single-photon detector made of superconducting nanowires. Four chips like this were used in the experiment that entangled three photons.

Unity in the Photon Community

The creation and detection of single photons (the smallest units of light) has grown in a few decades from an experimental laboratory pursuit to an important
