Researchers from Louisiana State University have introduced a smart quantum technology for the spatial mode correction of single photons. In a paper featured on the cover of the March 2021 issue of Advanced Quantum Technologies, the authors exploit the self-learning and self-evolving features of artificial neural networks to correct the distorted […]

Physicists from MIPT and Vladimir State University, Russia, have achieved a nearly 90% efficiency converting light energy into surface waves on graphene. They relied on a laser-like energy conversion scheme and collective resonances. The […]

Credit: University of Oxford The exponential growth of data traffic in our digital age poses some real challenges on processing power. And with the advent of machine learning and AI in, for example, self-driving vehicles and speech recognition, […]

Highly efficient, pure-blue organic light-emitting diodes (OLEDs) developed by researchers at Kyushu University in Japan are being tested to measure their lifetime. Based on hyperfluorescence, which uses a two-molecule process to emit light, the OLEDs emit pure-blue emission and exhibit significantly improved lifetimes compared to other highly efficient devices, all […]

Annular holes in a thin gold film filled with silicon dioxide enable ultrastrong coupling between light and atomic vibrations. This structure provides opportunities to probe molecules interacting with quantum vacuum fluctuations and develop novel optoelectronic devices.

Fiber optics couple laser light directly into the ion-trap chip. When in use, the chip is cooled to cryogenic temperatures in a vacuum chamber, and waveguides on the chip deliver the light to an ion trapped right above the chip’s surface for performing quantum computation.
