Subatomic particles such as quarks can pair up when linked by ‘strings’ of force fields — and release energy when the strings are pulled to the point of breaking. Two teams of physicists have now used ...

Quantum computers are beginning to become powerful tools for studying some of the most fundamental forces in the universe – and some of the trickiest to understand. Two experiments have used them to ...

Scientists may have uncovered the missing piece of quantum computing by reviving a particle once dismissed as useless. This particle, called the neglecton, could give fragile quantum systems the full ...

Researchers created scalable quantum circuits capable of simulating fundamental nuclear physics on more than 100 qubits. These circuits efficiently prepare complex initial states that classical ...

Quantum computers, systems that process information leveraging quantum mechanical effects, are expected to outperform classical computers on some complex tasks. Over the past few decades, many ...

Besides expanding our understanding of foundational physics, the team's breakthrough has significant potential applications in fields such as quantum information and quantum computing. Discover the ...

Governments and tech companies continue to pour money into quantum technology in the hopes of building a supercomputer that can work at speeds we can't yet fathom to solve big problems. Imagine a ...

Quantum computing has long felt like a perpetual promise — a mysteriously powerful technology that’s always “about 10 years away.” If you tuned it out, you weren’t alone. But something has shifted ...

On May 7, 1981, influential physicist Richard Feynman gave a keynote speech at Caltech. Feynman opened his talk by politely rejecting the very notion of a keynote speech, instead saying that he had ...
