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 ...

Researchers have successfully used a quantum algorithm to solve a complex century-old mathematical problem long considered impossible for even the most powerful conventional supercomputers. The ...

The course aims to give a brief and self-contained introduction to the mathematical methods of quantum mechanics. Although the materials are related to physics, they are presented in a more ...

Researchers at the University of Southern California (USC) in the US turned to an often overlooked particle for storing and processing quantum information to overcome the fragility of quantum ...

An experimental computer made by a Canadian company has proved its ability to solve increasingly complex mathematical problems. But the question remains — just how much of this calculating power is ...

Quantum computing is a lot to wrap your mind around. To put things very simply (as Canadian Prime Minister Justin Trudeau did recently, with surprising eloquence) regular computers are made up of bits ...

Quantum computers could soon be able to solve genuinely useful mathematical problems faster than classical computers, claims quantum computing firm Quantinuum. It would be the first example of these ...

Enormous disks of stars or debris can operate under the same rules as subatomic particles, changing based on the Schrodinger equation, which physicists use to model quantum-mechanical systems. Viewing ...

The original version of this story appeared in Quanta Magazine. Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the ...
