IBM (IBM): The superconducting-qubit leader is now pushing for an algorithmic edge that reduces cost on hard math. Alphabet/Google ( GOOGL ): Its quantum AI division just hit breakthrough error- ...

The uncertainty inherent to quantum mechanics has long left physicists wondering whether the observations we make on the ...

Building a working quantum internet would require overcoming a host of technical challenges, but researchers who have built ...

Recent decades have witnessed remarkable progress in establishing rigorous mathematical frameworks for quantum field theory (QFT), conformal field theory (CFT), quantum gravity and string theory.

Currently no commercially viable quantum computer exists. While a usable, functional quantum computer may exist in a few months, years, or even a few millenia (or a superposition of these states) we ...

Ernst Mach found atoms useful. But he didn’t believe they were real. The 19th century physicist-philosopher gained his greatest fame as an atom denier. He believed that reality consisted of sounds and ...

Although quantum computing enterprises IonQ and Rigetti were previously all the rage, both have encountered sharp volatility ...

Quantum computing may prove to be an existential threat to Bitcoin, but human panic and slow preparation are bigger ...

People often say that quantum physics is weird because it doesn’t seem rational. But of course, if you think about it, quantum physics is actually perfectly rational, if you understand the math. It’s ...
