D-Wave Achieves Significant Milestone with Calibration of 4,400+ Qubit Advantage2 Processor

New processor delivers exceptional performance gains over current Advantage system with doubled coherence and 40% increase in energy scale for advanced problem solving

PALO ALTO, Calif. - November 6, 2024 - D-Wave Quantum Inc. (NYSE: QBTS) ("D-Wave" or the "Company"), a leader in quantum computing systems, software, and services and the world's first commercial supplier of quantum computers, today announced that it has completed the calibration and benchmarking of a 4,400+ qubit Advantage2™ processor. This milestone marks a significant step forward in D-Wave's ongoing development of its sixth-generation annealing quantum computing system. The latest Advantage2 processor shows substantial performance gains over the current AdvantageTM system in solving customers' complex computational problems in areas such as optimization, AI, and materials science.

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 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.

Compared with the current Advantage system, the 4,400+ qubits Advantage2 processor delivers significant improvements in:

•Qubit coherence time: doubled, which drives faster time to solution

•Energy scale: increased by 40% to deliver higher-quality solutions

•Qubit connectivity: increased from 15 to 20-way connectivity to enable solutions to larger problems

"Our strategic decision to focus development efforts on enhancing the connectivity and coherence of our next annealing quantum computing system has proven successful," said Trevor Lanting, chief development officer at D-Wave. "We're thrilled with the performance of our recently calibrated processor, and we believe this technology will deliver amazing results for our customers, solving bigger and more complex problems."
