Quantum tunnelling — when a particle skips through a barrier that classical physics would forbid — happens faster when objects have less energy, find physicists who worked out a way to probe photons ...

Nobel Prize winners show how superconducting circuits can exhibit quantum behavior, leading to transformative technologies.

Quantum field theory (QFT) is a physics framework that describes how particles and forces behave based on principles rooted in quantum mechanics and Albert Einstein's special relativity theory. This ...

Have you ever felt confused by quantum physics? Ever thought you've read enough and still don't understand quantum physics? Don't worry, you're not alone! Even the world's best scientists don't ...

A team of theoretical researchers used thermal effective theory to demonstrate that quantum entanglement follows universal rules across all dimensions. Their study was published online in Physical ...

This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum mechanics was proposed. The theory hardly needed the extra publicity, though ...

Researchers explain why weak magnetic fields can instantly control electrical flow direction in these quantum metals.

A conveyor belt of atoms arranged in orderly rows could resolve a major stumbling block towards developing a large-scale quantum computer. Quantum-computing technology that makes qubits from atoms ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

A major breakthrough in quantum technology was achieved in October 2024: the first-ever quantum satellite communication link between China and South Africa. The connection spanned a remarkable ...

When a molecule of tryptophan absorbs ultraviolet light, it glows faintly as it lets off lower-frequency energy. This soft glow, known as fluorescence, is a familiar effect. But when many tryptophan ...

Quantum physics isn’t just complicated – after 100 years, there is an awful lot of it to understand. This makes writing an accessible yet comprehensive book about the topic a challenge in both ...
