IBM and collaborators say their quantum computers outperform all known classical algorithms for three distinct tasks, but ...

There are many algorithms for which it has been mathematically proven that a quantum computer can generate results that would ...

IBM and researchers from the University of Chicago announced a demonstration in quantum computing that meets the fundamental ...

If the goal is to make quantum systems act like powerful classical machines, then today’s quantum computers may be too ...

D-Wave quantum supremacy challenged: Flatiron Institute physicists showed that a classical algorithm using 3D tensor networks and a revived 1982 belief propagation method can match spin glass dynamics ...

Michael Osei is interested in whether a quantum computer is fast but also does it produce reliable, high-quality, ...

Earlier this year, researchers at the Flatiron Institute's Center for Computational Quantum Physics (CCQ) announced that they had successfully used a classical computer and sophisticated mathematical ...

A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware. Researchers used tensor networks to compress the overwhelming wave function ...

Although quantum processors exist today, they are still a long way off from becoming practical replacements for classical computers. This is due to many practical considerations, not the least of ...

EY quantum computer installation marks a Big Four first: EY Canada now physically owns on-site quantum hardware in Toronto, ...

Researchers have invented a new method by which classical computers can measure the error rates of quantum machines without having to fully simulate them. Quantum ...

Big Four firm Ernst and Young announced it now has a quantum computer physically sitting in its Toronto office.
