Using microbrewery waste to synthesize carbon quantum dots

For a few years now, spent grain, the cereal residue from breweries, has been reused in animal feed. This material could also be used in nanotechnology. Professor Federico Rosei's team at the Institut national de la recherche ...

Twin photons from different quantum dots

Identical light particles (photons) are important for many technologies that are based on quantum physics. A team of researchers from Basel and Bochum has now produced identical photons with different quantum dots—an important ...

Introducing the largest quantum photonic processor to date

Quantum computers promise to propel computing far beyond what today's computers are capable of, but this potential has yet to be realized. In their search for a way to demonstrate quantum supremacy, researchers working in ...

Molecular dance by which a unique bacterium transfers electrons

Imagine you wanted to plug a device into an outlet on your wall, but you didn't have a cord that reached all the way. Instead, all you had were short snippets of wire that, put together, weren't enough to cover the distance ...

Quantum dot

A quantum dot is a semiconductor whose excitons are confined in all three spatial dimensions. As a result, they have properties that are between those of bulk semiconductors and those of discrete molecules. They were discovered by Louis E. Brus, who was then at Bell Labs. The term "Quantum Dot" was coined by Mark Reed.

Researchers have studied quantum dots in transistors, solar cells, LEDs, and diode lasers. They have also investigated quantum dots as agents for medical imaging and hope to use them as qubits.
