In a study, physicists now observed a class of quantum particles called fractional excitons, which behave in unexpected ways and could significantly expand scientists' understanding of the quantum ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in ...

The original version of this story appeared in Quanta Magazine. For computer scientists, solving problems is a bit like mountaineering. First they must choose a problem to solve—akin to identifying a ...

It’s been difficult to find important questions that quantum computers can answer faster than classical machines, but a new algorithm appears to do it for some critical optimization tasks. For ...

A tiny device that entangles light and electrons without super-cooling could revolutionize quantum tech in cryptography, computing, and AI. Present-day quantum computers are big, expensive, and ...

Retired professor Rishi Kumar Singhal teaches physics through Hindi poetry, using 250 poems across four books to simplify ...

MIT physicists and colleagues have for the first time measured the geometry, or shape, of electrons in solids at the quantum level. Scientists have long known how to measure the energies and ...

More than 30 years ago, researchers discovered that hypothetical computers based on the laws of quantum physics would be able to rapidly solve difficult math problems. Ever since then, they’ve sought ...
