HBT Measurement

Type: Concept

As of November 2026, HBT Measurement has been mentioned in one podcast episode on Cell Press (Jan 2026). Mentioned as a method to measure single photon emission features.

In physics, the Hanbury Brown and Twiss (HBT) effect is any of a variety of correlation and anti-correlation effects in the intensities received by two detectors from a beam of particles. HBT effects can generally be attributed to the wave–particle duality of the beam, and the results of a given experiment depend on whether the beam is composed of fermions or bosons. Devices which use the effect are commonly called intensity interferometers and were originally used in astronomy, although they a
