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 ...

The researchers need to prepare the qubits and the photon so the modules "share" the photon at the end of the protocol. The ...

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 ...

Procedures such as X-rays; computed tomography (CT); magnetic resonance imaging (MRI); positron emission tomography (PET) and single-photon emission computed tomography (SPECT) are important in ...

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 ...
