Three photons at once beat the standard photon test

Дата публикации: 17-08-2026 20:00:05

Physicists at the University of Twente have improved the standard test for the quality of individual particles of light. By letting three photons interfere at the same time instead of two, they draw more information from every measurement. Their experiment outperforms even a perfect, noise-free run of the old method. The work appeared in Physical Review Letters.
