TechRepublic: D-Wave's 2000Q variant reduces noise for cloud-based quantum computing

James Sanders

"This week, Quantum computing firm D-Wave Systems announced a revised version of the 2000Q quantum annealer that aims to reduce noise. The revised D-Wave 2000Q is available immediately in the D-Wave Leap quantum cloud service, though it is not available for on-premises deployment—the manufacturing refinement that enabled this will be used for the company's next-generation platform.

The effects of noise on quantum computers can be highly detrimental, even in small quantities. Computations on current quantum hardware are limited by a relatively short coherence time—the amount of useful operational time in a calculation before information is lost—and circuit depth, which measures the number of sequential operations that can be performed."
