One of the most striking features of quantum physics is that certain properties cannot be measured at the same time. Every measurement may inevitably affect the object's physical state being ...

Quantum computers need special materials called topological superconductors—but they’ve been notoriously difficult to create. Researchers have now shown they can trigger this exotic state by subtly ...

Quantum computing in 2026 still isn't a faster laptop. It doesn't make email snappier, and it won't speed up spreadsheets.

The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum computer: The realization of a novel type of quantum logic gate makes it ...

Quantum entanglement can link two objects even when they are separated by extremely large distances. But a new study has found a limit at which such quantum correlations stop – and surprisingly, ...

(Nanowerk News) Although systems consisting of many interacting small particles can be highly complex and chaotic, some can nonetheless be described using simple theories. Does this also pertain to ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the smallest scales, erasing information is not free, it consumes energy and ...

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 ...

Welcome to the Physics World Quantum Briefing 2.0, which wraps up the International Year of Quantum Science and Technology (IYQ) and looks ahead to a quantum-enhanced future. This second instalment ...
