Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

Simulations of quantum many-body systems are an important goal for nuclear and high-energy physics. Many-body problems involve systems that consist of many microscopic particles interacting at the ...

As long as there's been an internet, there's been a way to hack it. Scientists have spent decades imagining a different kind of network, one where the laws of physics make eavesdropping physically ...

Lead author Dr Angus Gale says the research gives scientists a new control mechanism for tiny quantum light sources, bringing them a step closer to ...

A team of physicists has shown that quantum-encrypted keys can travel 75 miles through the same fiber-optic cable already carrying ordinary internet traffic, removing one of the biggest practical ...

Scientists have created a powerful new way to control quantum systems, achieving the first-ever demonstration of quadsqueezing—an elusive fourth-order quantum effect. By combining simple forces in a ...

A long-standing challenge in physics has been to integrate gravity into the Standard Model, which successfully describes the electromagnetic, weak, and strong forces. The difficulty lies in the ...

For the first time, scientists have observed the iconic Shapiro steps, a staircase-like quantum effect, in ultracold atoms. In a recent experiment, an alternating current was applied to a Josephson ...

In a study, physicists now observed a class of quantum particles called fractional excitons, which behave in unexpected ways and could significantly expand scientists' understanding of the quantum ...

A new quantum algorithm ran a 15-step nonlinear fluid simulation around a solid obstacle on real quantum hardware, the most physically complex publicly documented demonstration of its kind. The ...

Machine learning models called convolutional neural networks (CNNs) power technologies like image recognition and language translation. A quantum counterpart—known as a quantum convolutional neural ...
