Physicists have figured out how to get pure and bright single photons without compromise.

Typically, single-photon sources suffer from a trade-off: the purer the photon, the weaker the signal. A new method uses triple interaction to deliver perfectly pure photons at high brightness even in noisy conditions. It's like a turnstile that blocks pairs but operates fast. A step toward ideal quantum devices.

🎯 To notice light, the eye needs at least ten photons at once—a single one remains completely invisible.
