The quantum world has a reputation for being elusive, but physicists are now starting to watch it unfold in real time. For ...

The findings not only advances scientists' understanding of what quantumness really means over time, but also points to new ...

By building an atomic equivalent of the critical Josephson junction, scientists can now study how energy is lost and excitations form.

If you’re an avid nonfiction reader the last 25 years, the name Kate Shoup may already ring a bell. Inspired by watching her ...

Wall Street's hottest trend in 2025 appears primed for significant disappointment in the new year. For three years, artificial intelligence (AI) has been the premier growth trend on Wall Street.

Some critics argue the threat posed by quantum computers is overblown, including Strategy chairman Michael Saylor, who has once called it a marketing ploy to pump quantum-branded tokens. Bitcoin OG ...

A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth ...

Quantum computers based on ions or atoms have one major advantage: The qubits themselves aren’t manufactured, and there’s no device-to-device variability among atoms. Every atom is the same and should ...

Designed to accelerate advances in medicine and other fields, the tech giant’s quantum algorithm runs 13,000 times as fast as software written for a traditional supercomputer. A quantum computer at ...

Two physicists at the University of Stuttgart have proven that the Carnot principle, a central law of thermodynamics, does not apply to objects on the atomic scale whose physical properties are linked ...

The very first computer to make use of the bizarre and unintuitive properties of quantum mechanics was born out of a collaboration between major universities and International Business Machines (IBM ...
