Two-photon emission (2PE) is a process in which an electron transition between quantum levels occurs through the simultaneous emission of two photons. Two-photon emission is interesting because it ...

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.

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

Researchers at Montana State University, in collaboration with Columbia University and the Honda Research Institute, have demonstrated the emission of single photons from a new type of quantum ...

A recent study in Advanced Optical Materials introduces a hybrid electroluminescence device capable of generating single photons on demand at room temperature. This development addresses a ...

On the way to overcoming these challenges, MIT researchers developed a new interconnect device that can support scalable, ...

If an electron is in an excited state it can return to a lower energy level. When it does this, it loses energy. The amount of energy it loses will be equal to the difference in the energy levels ...

Cancer diagnosis frequently requires imaging studies that in many cases use small amounts of radiation. Procedures such as X-rays; computed tomography (CT); magnetic resonance imaging (MRI); positron ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ...
