Researchers at ETH have studied in detail how single moving electrons can cause a material to become magnetic. Using quantum simulators, researchers in the U.S. have created images made of coloured ...

Physicists in Germany have developed a new method for generating tunable wavelengths, as well as more easily switching back and forth between two wavelengths, employing quantum-dot lasers. The finding ...

Colloidal quantum dots (QDs) constitute a platform to explore various quantum effects. Their size-dependent colors are essentially a naked-eye, ambient-condition visualization of the quantum ...

Assemblies of quantum dots — blobs of a few thousand atoms — with electrons shuttling between them could form miniature low-power computing circuits that do not require transistors. But these ...

Hybrid structures containing semiconductor quantum dots and metal nanoparticles could lead to better light-emitting diodes and new nonlinear photonic devices. That is according to researchers in China ...
