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 July 30 a demonstration in quantum computing that meets the ...

A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware.

IBM and University of Chicago researchers have demonstrated a quantum computing system that they ...

D-Wave quantum supremacy challenged: Flatiron Institute physicists showed that a classical algorithm using 3D tensor networks ...

An illustration of a quantum system that was simulated by both classical and quantum computers. The highlighted sections show how the influence of the system’s components is confined to nearby ...

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 ...

Paradoxically, reports of powerful quantum computations are motivating improvements to classical ones, making it harder for quantum machines to gain an advantage. “Most of the time when people talk ...

To this day, we have yet to see a quantum computer conclusively perform a single useful task. Existing machines are simply too small and error-ridden to solve commercially relevant problems. That hasn ...

Rigetti will deliver a 9-qubit Novera™ quantum computing system to the new Pittsburgh Supercomputing Center testbed, which is being funded by a ...

From punch card-operated looms in the 1800s to modern cellphones, if an object has “on” and “off” states, it can be used to store information. In a laptop computer, the ones and zeroes that make up ...
