A pair of physicists at the University of California, Riverside, are aiming to convert light falling on atomically thin semiconductor materials into electricity, having received more than $582,000 in funding from the U.S. Department of the Army.
The ability to turn on and off a physical process with just one photon is a fundamental building block for quantum photonic technologies.
Researchers from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences analyzed the high-loss, free-space, high-precision time-frequency dissemination experiment between remote locations.
Diodes are widely used electronic devices that act as one-way switches for current. A well-known example is the LED (light-emitting diode), but there is a special class of diodes designed to make use of the phenomenon known as "quantum tunneling".
Astronomers are finding ways for smart alternatives to keep answering basic questions in physics after experiencing the devastating loss of the Arecibo Observatory in Puerto Rico and the usually prohibitive cost of satellite missions.
The use of information technology in which the spin of electrons is used for information processing in quantum computers might be possible in the future.
If you're looking for one technique to maximize photon output from plasmons, stop. It takes two to wrangle.
Nonlinear optics, a study of how light interacts with matter, is critical to many photonic applications, from the green laser pointers we're all familiar with to intense broadband (white) light sources for quantum photonics that enable optical quantum computing, super-resolution imaging, optical sensing and ranging, and more.
In a potential boost for quantum computing and communication, a European research collaboration reported a new method of controlling and manipulating single photons without generating heat. The solution makes it possible to integrate optical switches and single-photon detectors in a single chip.
Recently, the Laboratory of Micro and Nano Engineering, School of Engineering Science, University of Science and Technology of China (USTC) has made important progress in the field of structural chirality detection research using vortex light and found that photon orbital angular momentum can efficiently detect the optical chiral signal of structures.
