Devices that can confine individual electrons are potential building blocks for quantum information systems. But the electrons must be protected from external disturbances. RIKEN researchers have now ...

For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs of entangled photons. By carefully tailoring the photonic environment ...

Researchers have found a clever way to make quantum dots, tiny light-emitting crystals, produce streams of perfectly controlled photons without relying on expensive, complex electronics. By using a ...

In one sentence: A quantum dot laser is a semiconductor laser whose gain medium contains nanoscale quantum dots that confine electrons and holes in all three dimensions, producing discrete energy ...
