Researchers create powerful quantum source with meta-lens array

Researchers for the first time have demonstrated a quantum light source based on a meta-lens array. The approach offers a promising platform for both high-dimensional photon entanglement and the coherent control of multiple ...

Method uses radio signals to image hidden and speeding objects

Researchers at the National Institute of Standards and Technology (NIST) and Wavsens LLC have developed a method for using radio signals to create real-time images and videos of hidden and moving objects, which could help ...

Quantum holds the key to secure conference calls

The world is one step closer to ultimately secure conference calls, thanks to a collaboration between Quantum Communications Hub researchers and their German colleagues, enabling a quantum-secure conversation to take place ...

Team directs and measures quantum drum duet

Like conductors of a spooky symphony, researchers at the National Institute of Standards and Technology (NIST) have "entangled" two small mechanical drums and precisely measured their linked quantum properties. Entangled ...

Evading the uncertainty principle in quantum physics

The uncertainty principle, first introduced by Werner Heisenberg in the late 1920's, is a fundamental concept of quantum mechanics. In the quantum world, particles like the electrons that power all electrical product can ...
