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 proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, uses number ...

Quantum information and computation is a very active interdisciplinary area between math, physics, and computer science. Quantum error correction plays a central role ...

Light-based quantum circuit does basic maths Researchers from the University of Queensland have taken a significant step in the quest to build a quantum computer, creating a light-based quantum ...

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 ...

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 ...

IonQ announces a new world record – achieving 99.99% two-qubit gate fidelity. Here’s why that milestone warrants buying IONQ ...

That's why I'm leaning toward the exchange-traded fund (ETF) approach. One particular quantum computing ETF that has found ...

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

Is the world’s first commercial quantum computer the real deal or not? No one is quite sure. The most recent experiment adding fodder to this debate used the quantum computer made by the Canadian ...

Hands up, who remembers D-Wave? No? Well, don't worry; it's still around. D-Wave is a company that is pursuing the development of a scalable quantum computer. And, just in case you forgot about them, ...
