A new study published in Nature Communications has shown that in the asymptotic limit, extracting the maximum possible work ...

The findings are currently theoretical but could be tested experimentally, says Luis Pedro García-Pintos, a physicist at Los ...

In the pursuit of powerful and stable quantum computers, researchers at Chalmers University of Technology, Sweden, have developed the theory for an entirely new quantum system – based on the novel ...

An “echo” that arrives before you finish speaking sounds like a glitch. In quantum hardware, that kind of self-interference can be a feature. That odd timing sits at the heart of a new theoretical ...

Quantum computing is a largely theoretical, ultimately expensive proposition for high-level computation. However, new ...

In quantum mechanics, particles do not behave like everyday objects. Instead of existing in one clearly defined state, they ...

Cisco has shown a Universal Quantum Switch prototype designed to connect different quantum computers and sensors over ...

Slight temperature changes, imperceptible manufacturing imperfections, and heat generated by their own components can completely ruin an entire quantum quantum system-on-chip. Silicon photonics could ...

For decades, quantum computing has been heralded as a technology of the future, promising to solve problems far beyond the reach of supercomputers. But its practical use has remained elusive. That’s ...

Rigetti Computing has announced the general availability of its most powerful quantum computer to date, rounding off months of uncertainty. Shares were getting a much-needed boost on Wednesday. The ...
