They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...

For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art quantum computers have around 1,000 qubits. Columbia physicists Sebastian ...

There’s only a few days left in the International Year of Quantum Science and Technology, but we’re still finding plenty to celebrate here at Physics World HQ thanks to a long list of groundbreaking ...

A thought experiment that was at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally been made real. Its findings elucidate one of the core mysteries ...

They managed to cut the size of the AI reasoning model by more than half—and claim it can now answer politically sensitive questions once off limits in Chinese AI systems. A group of quantum ...

Despite its simplicity, the model is foundational. It is often the first non-trivial system for which students solve the Schrödinger equation exactly, and it beautifully illustrates core quantum ideas ...

Quantum computing leverages qubits' unique properties to revolutionize computing power, driving transformative impacts across industries and shaping the future of technology. Pixabay, geralt Quantum ...

Physicists are still puzzling over the true nature of dark matter and dark energy, because they have inexplicably added 10 times as much mass as normal matter has to the universe. Looking at the ...

Two physicists at the University of Stuttgart have proven that the Carnot principle, a central law of thermodynamics, does not apply to objects on the atomic scale whose physical properties are linked ...

On Tuesday the field of quantum mechanics received a thoughtful 100th-birthday present from the Royal Swedish Academy of Sciences: three shiny new medals, 11 million Swedish kronor (to be divided ...
