Physicists show knotted cosmic strings may have dominated the early universe before collapsing to create matter—a theory ...

IBM (IBM): The superconducting-qubit leader is now pushing for an algorithmic edge that reduces cost on hard math. Alphabet/Google ( GOOGL ): Its quantum AI division just hit breakthrough error- ...

AI focuses on learning patterns from data to make decisions; quantum computing focuses on raw computational power for complex problems like molecular simulation and code-breaking.

Can two versions of reality exist at the same time? Physicists say they can — at the quantum level, that is. Fact check: 18 ...

Researchers at tech giant IBM ($IBM) have developed a new quantum algorithm that shows a notable speed advantage over the best classical methods, ...

The proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, uses number ...

The uncertainty inherent to quantum mechanics has long left physicists wondering whether the observations we make on the ...

Clarke, Devoret, and Martinis win 2025 Nobel Physics Prize for making quantum mechanics tangible. They showed quantum tunneling and energy quantisation in superconducting circuits. Prize marks quantum ...

Recent progress in both analog and digital quantum simulations heralds a future in which quantum computers could simulate — and thereby illuminate — physical phenomena that are far too complex for ...

Libby Heaney’s Growler (2024) is a glass sculpture that looks anything but. Despite its crystalline surface, it appears as if viscous, gummy and glutinous as it sags and drips down the side of its ...

In 1951, physicist Julian Schwinger theorized that by applying a uniform electrical field to a vacuum, electron-positron pairs would be spontaneously created out of nothing, through a phenomenon ...
