Scientists are using light waves to accelerate supercurrents and access the unique properties of the quantum world, including forbidden light emissions that one day could be applied to high-speed, quantum computers, communications and other technologies.

The scientists have seen unexpected things in supercurrents – electricity that moves through materials without resistance, usually at super cold temperatures – that break symmetry and are supposed to be forbidden by the conventional laws of physic...

An international research team led by scientists at the University of California, Riverside, has observed light emission from a new type of transition between electronic valleys, known as intervalley transmissions. The research provides a new way to read out valley information, potentially leading to new types of devices.

Current semiconductor technology uses electronic charge or spin to store and process information; the associated technologies are called electronics and spintronics, respectively...

LiDAR is a technique used for measuring distances with laser light. Researchers now show a new way to speedup a type of LiDAR engine by using photonic circuits. Light detection and ranging (LiDAR) comprised an array of techniques using laser light to measure distances by multiplying the time delay between transmitted and received optical signals with the speed of light. Modern 3D LiDAR sensors combine high lateral/vertical and radial resolution, and are key components in the ongoing revolution of level 4 and 5 self-driving cars.

The prominence of 3D LiDAR...

Physicists at the Institute of Science and Technology Austria (IST Austria) have invented a new radar prototype that utilizes quantum entanglement as a method of object detection. This successful integration of quantum mechanics into our everyday devices could significantly impact the biomedical and security industries. The research is published in the journal Science Advances.

Quantum entanglement is a physical phenomenon where two particles remain inter-connected, sharing physical traits regardless of how far apart they are from one another...
