Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, ...

I keep coming back to a strange idea: what if everything we know about quantum physics is already encoded inside a single atom? Not in a mystical sense, but in the very real way that one tiny system ...

Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

Physics has a reputation for being dominated by men, especially a century ago, as quantum physics was just being invented – ...

The algorithms could also benefit AI by generating large, diverse datasets to train models or by enabling quantum-enhanced machine learning, says Adam Lewis, the head of innovation at SandboxAQ, a ...

Teleportation is a reality in 2025 — well, at least for quantum computers. In February 2025, Oxford University demonstrated the teleportation of quantum data from one independent quantum processor to ...

This repository aims to contain definitions and proofs of basic ideas in quantum information theory. Some major goals, in rough order of difficulty, would be ...

The nature of gravity — and whether it can be reconciled with quantum mechanics — is one of the biggest mysteries in physics. Most researchers think that at a fundamental level, all phenomena follow ...

I have long been fascinated by the strong attraction many people feel toward quantum field theory as a way to explain extraordinary experiences. As a psychiatrist interested in coincidences and the ...

HSBC used IBM's quantum computers to improve a process involved in algorithm bond trading. The collaboration demonstrated that pairing quantum computers with classical techniques can provide ...

International Business Machines (NYSE: IBM) has been working on quantum computing technology for decades. The company's quantum computing roadmap calls for a demonstration of quantum advantage, where ...
