Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the ...
The low-noise, high-gain properties needed for high-performance quantum computing can be realized in a microwave photonic circuit device called a Josephson traveling-wave parametric amplifier (JTWPA), ...
On 4 February, techUK hosted the latest instalment of its Quantum Readiness Series, bringing together experts from across the UK’s quantum ecosystem to explore how rapidly developing quantum ...

Laser-written glass chip brings quantum communication to real-world use
Quantum communication has long promised unbreakable encryption, but the hardware has struggled to escape the lab. A new generation of laser-written glass chips is changing that equation, carving three ...
In 2024, a quantum state of light was successfully teleported through more than 30 kilometers (around 18 miles) of fiber ...
Abstract: Currently the development of quantum computers is active; however, large-scale machines remain limited and noisy. Furthermore, such quantum computers do not allow direct access to state ...
Abstract: The goal of the quantum-computing industry is to build a powerful, functional machine capable of solving large-scale problems in science and industry that classical computing can't solve. We ...
John Martinis is a hardware guy. He prefers the nitty-gritty of doing physics in the lab over the idealised world of textbooks. But you couldn’t write the quantum computing history books without him: ...
A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing ...
Researchers at Academia Sinica have developed a 20-qubit superconducting quantum computer, marking Taiwan’s entry into large-scale quantum chip fabrication. The system was designed, fabricated, and ...
