How 'Quantum Dots' Could Probe Mysteries of Entanglement

A microwave laser built using tiny particles that act as semiconductors could be used to explore strange phenomena such as quantum entanglement.

Researchers at Princeton University used quantum dots — tiny particles of light-emitting nanocrystals that can absorb light from one wavelength and convert it to highly saturated light at specific wavelengths — to build a so-called "maser" that emits light at longer wavelengths than the traditional ...
