D-Wave Speeds Up Quantum Computers Over 25 Times With Low-Noise Materials
D-Wave has made quantum annealing computing chips using different materials which reduced noise and increase speed by 25 times. The reduced noise improved performance with more than a 25x speed up in solving spin glass problems.
They are continuing efforts to reduce noise in D-Wave QPUs. The experimental fabrication stacks examined in this study are but an intermediate step in an ongoing effort to improve D-Wave’s technology. They anticipate that additional and more substantial modifications currently being driven by detailed materials science investigations will imminently be qualified for full-scale manufacturing.
In May, 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.
