Photon purity is more than a technical detail. In photonic quantum computing, orderly single-photon streams are easier to ...

A new discovery shows that messy, stray light can be used to clean up quantum systems instead of disrupting them. University ...

Researchers at the University of Iowa have identified a new way to "purify" photons, a development that could improve both the performance and ...

A NASA laser just fired successfully in a deep-space test. On Nov. 14, NASA picked up a laser signal fired from an instrument that launched with the Psyche spacecraft, which is currently more than 10 ...

Laser linewidth measures how precisely a beam of light maintains its frequency and color purity. The narrower the linewidth, the more monochromatic and spectrally pure the laser. The team's ...

Prototype quantum photonic-dimer laser uses entanglement to bind photons and deliver a powerful beam of concentrated light that can shine through adverse weather like thick fog. When you purchase ...
