Monster 4,400-qubit quantum processor is '25,000 times faster' than its predecessor

D-Wave says its new Advantage2 processor, which is designed for complex applications in AI, optimization and data science, is faster and more accurate than its existing 5,000-qubit system.

D-Wave has completed calibrating and benchmarking its latest processor — a 4,400-plus-qubit behemoth that it claims is 25,000 times faster than its predecessor.

The Advantage2 quantum processing unit (QPU) is designed for complex applications including artificial intelligence (AI), materials science and optimization tasks. In a statement issued Nov. 6, D-Wave representatives said the new chip demonstrated "substantial performance gains" over its existing 5,000-qubit Advantage device, including improved speed and accuracy.

"Recent performance benchmarks demonstrate that the 4,400+ qubit Advantage2 processor is computationally more powerful than the current Advantage system, solving a range of problems — including 3D lattice problems common in materials science — 25,000 times faster," the company said in the statement. "The processor also delivers five times better solutions on problems requiring a high degree of precision. Furthermore, it surpasses the current Advantage system in 99% of tests on satisfiability problems, highlighting its capabilities across a wide range of quantum applications."

3D lattice problems are often used in materials science to model atomic interactions. Faster solutions mean researchers can conduct these simulations more quickly, which supports faster development and testing of new materials.
