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 designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

Mid-infrared light sources serve as a key to accessing the “invisible world.” A broad range of applications, including gas detection, molecular spectroscopy, medical diagnostics, and free-space ...
