Just a few years ago, many researchers in quantum computing thought it would take several decades to develop machines that ...

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 ...

By using controlled microwave noise, researchers created a quantum refrigerator capable of operating as a cooler, heat engine, or amplifier. This approach offers a new way to manage heat directly ...

Quantum computing has the attention of the most powerful institutions in the world, including Google, Microsoft, Amazon, IBM and the U.S. government. Startups in the space attracted about $2 billion ...

The unveiling by IBM of two new quantum supercomputers and Denmark's plans to develop "the world's most powerful commercial quantum computer" mark just two of the latest developments in quantum ...

Quantum computing is moving from physics labs into real hardware, promising to attack problems that overwhelm even the fastest supercomputers. Among the boldest claims is that these machines could ...

Quantum computers are shifting from lab curiosities into real machines that can already outperform classical systems on narrow tasks, and the stakes are no longer theoretical. The technology promises ...
