Atomically precise sources promise new quantum optical applications. A “color center” being created in a carbon nanotube. Tiny tubes of carbon that emit single photons from just one point along their ...

Quantum light sources often produce inconsistent or contaminated single photons, limiting the reliability of quantum technologies. Researchers coated atomically thin tungsten diselenide with a uniform ...

The schematic diagram of the single-photon source system and the efficiency of the single-photon source surpassing the loss tolerance threshold. (Image by PAN et al.) Research teams led by Prof. PAN ...

Quantum emission is a fundamental process in which a quantum system, such as an atom, molecule, or quantum dot, releases energy in the form of photons. This phenomenon is governed by the laws of ...

Quantum technologies demand perfection: one photon at a time, every time, all with the same energy. Even tiny deviations in the number or energy of photons can derail devices, threatening the ...
