A method to make quantum dots lets them release single photons. The approach could support quantum communication systems.

Light-based quantum technologies, such as quantum communication and photonic quantum computing, require reliable sources of individual photons and, ideally, pairs of entangled photons. Semiconductor ...

Scientists have developed a new way to manufacture semiconductor quantum dots that emit faster ...

Accurate alignment of quantum dots with photonic components is critical for extracting the radiation emitted by the dots. In this illustration, a quantum dot centered in the optical "hotspot" of a ...

(Nanowerk Spotlight) Quantum dots have been receiving extensive attention from researchers because they can be widely used for basic physics study, quantum computing, biological imaging, ...

For the first time in history, the production of semiconductor quantum dots has been achieved at room temperature using lab-designed proteins, Princeton chemists reported in a paper published in the ...

Still fluorescent: A sample of the supraparticles recycled in the experiment. (Courtesy: Dillon H Downie, University of Strathclyde) Researchers at the University of Strathclyde, UK, have developed a ...

Depending on their applications, quantum dots need to be tailored in terms of their structure and properties. Chemists have shown that quantum dots obtained by their novel method can be successfully ...
