Two-photon emission is a relatively weak emission process, about five orders of magnitude weaker than the usual single-photon emission that occurs in semiconductor lasers or LEDs. So we had to use ...

Quantum computers have the potential to solve complex problems that would be impossible for the most powerful classical ...

Single-photon emission from carbon nanotubes has been observed by researchers in Switzerland. The findings give hope for a new type of light source for quantum computing and quantum communication.

The Honda Research Institute synthesized these nanoribbons, which were stretched over specially designed Columbia University surfaces to stimulate photon emission. The MSU team conducted tests on ...

This study presents a hybrid device that integrates hBN nanocrystals with GaN/InGaN laser diodes for efficient room-temperature single-photon emission. Using a bottom-to-top excitation scheme ...

This means that each electron transition will produce a photon of a different frequency and hence a different colour. This causes line emission spectra to be produced, as shown below. This is not ...

This dwell time before re-emission is what is confusing to many ... If one were to think of this pulse as discrete quanta of photon particles, it’d seem to break causality, but as a wave ...
