Researchers just announced a breakthrough in OLED technology that could lead to brighter, more energy-efficient TVs. Here's ...

The two photons are emitted at complementary wavelengths. Another important method is to perform coincidence measurements. Because the photons are correlated, both photons are emitted at the same ...

Quantum emitters are nanoscale systems that can generate single photons or pairs of entangled photons on demand. These emitters are typically based on the optical transitions of individual quantum ...

Amplified spontaneous emission is a physical phenomenon that entails the amplification of the light spontaneously emitted by ...

This why the recent chatter in the media about researchers having discovered ‘negative time’ with photons being emitted before the sample being hit by source photons created such a stir.
