Scientists and researchers have long extolled the extraordinary potential capabilities of universal quantum computers, like simulating physical and natural processes or breaking cryptographic codes in ...

Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

For humans, background noise is generally just a minor irritant. But for quantum computers, which are very sensitive, it can be a death knell for computations. And because “noise” for a quantum ...

Quantum computers are fragile miracles of physics that are unreliable, cost-prohibitive, and more error-prone than a shortstop with no depth perception. But, if we ever want to get to Star Trek levels ...

Chemistry and physics researchers have advanced quantum simulation by devising an algorithm that can more efficiently calculate the properties of molecules on a noisy quantum computer. The large, ...

A new theoretical study involving EPFL shows how the noise in today’s quantum computers limits how much work their circuits can really do, and how this affects training and simulation.

Texas Instruments has a solution to the problem of hot and noisy computers: split them into two parts and move the hottest and loudest components off the desktop and away from the user. The idea of a ...
