Using polarization to improve quantum imaging

 Quantum Physics News
 20 March 2024
Quantum imaging is a growing field that takes advantage of the counterintuitive and "spooky" ability of light particles, or photons, to become linked, or entangled, under specialized circumstances. If the state of one photon in the entangled duo gets tweaked, so does the other, regardless of how far...

A method to accurately center quantum dots within photonic chips

 Quantum Physics News
 19 March 2024
Devices that capture the brilliant light from millions of quantum dots, including chip-scale lasers and optical amplifiers, have made the transition from laboratory experiments to commercial products. But newer types of quantum-dot devices have been slower to come to market because they require...

Cracking the quantum code: Simulations track entangled quarks

 Quantum Physics News
 19 March 2024
Today, the word "quantum" is everywhere—in company names, movie titles, even theaters. But at its core, the concept of a quantum—the tiniest, discrete amount of something—was first developed to explain the behavior of the smallest bits of matter and energy....

Elegant use of noise for quantum computing

 Quantum Physics News
 18 March 2024
Scientists around the world work hard to rinse quantum systems for noise, which may disturb the function of tomorrow's powerful quantum computers. Researchers from the Niels Bohr Institute (NBI) have found a way to use noise to process quantum information. This raises the performance of the quantum...
