SkyWater's Commercially Fabricated Qubits Power D-Wave's Landmark Achievement in Quantum Supremacy

SkyWater Technology, Inc. (NASDAQ:SKYT, or "SkyWater")), a U.S.-based Trusted technology realization partner, and D-Wave Quantum, Inc. (NYSE:QBTS, or "D-Wave")), a leader in quantum computing systems, software and services, today announced that D-Wave's Advantage2™ annealing quantum computer prototype, fabricated by SkyWater, was used to achieve computational supremacy in quantum simulation. The landmark research was published today by the American Association for the Advancement of Science (AAAS), in its journal, Science, one of the world's most respected scientific journals, known for publishing high-impact research that advances global scientific and technological progress. The article details the work which demonstrates that D-Wave's superconducting annealing quantum computing processors can efficiently solve problems beyond the practical reach of classical computers. This breakthrough also underscores the vital role of U.S.-based manufacturing in advancing global technology leadership.

The peer-reviewed paper, "Beyond-Classical Computation in Quantum Simulation," confirms that D-Wave's annealing quantum computer outperformed one of the world's most powerful classical supercomputers in solving complex magnetic materials simulation problems with relevance to materials discovery. Understanding the quantum nature of magnetic materials is crucial to finding new ways to use them for technological advancement, making materials simulation and discovery a vital area of research for D-Wave and the broader scientific community. Magnetic materials are widely used in medical imaging, electronics, superconductors, electrical networks, sensors and motors.

Through the ongoing partnership with D-Wave, which began a decade ago at the Minnesota fab, SkyWater has provided highly specialized process integration, materials engineering and thin film fabrication expertise, enabling D-Wave's concepts to be realized as manufacturable devices. SkyWater's advanced development capabilities, including custom material deposition, specialized device patterning and large-scale fabrication integration, together with D-Wave's superconducting materials and device expertise, have been integral in producing the qubits powering this major advancement.

Additionally, with SkyWater's DOD Trusted Foundry status and D-Wave's pioneering leadership in quantum computing, this partnership supports the rapidly growing commercialization of useful quantum computing solutions while reinforcing domestic leadership in advanced computing. U.S. semiconductor manufacturing strengthens national security, economic resilience and the country's leadership in the global race to develop advanced quantum capabilities. Furthermore, the milestone announced today highlights SkyWater's critical role in enabling innovators to conceive and scale next-generation advancements, underscoring the importance of expanding and safeguarding this crucial infrastructure to maintain U.S. leadership.

"We believe achieving quantum supremacy with qubits fabricated at SkyWater marks a pivotal moment for the entire quantum ecosystem," said Dr. Alan Baratz, CEO of D-Wave. "Our focus has always been on scalable, real-world quantum solutions, and our decade-long partnership has been instrumental in achieving this milestone. In our view, this collaboration showcases the strength of American innovation and demonstrates the critical role of domestic manufacturing for maintaining global technology leadership."

"SkyWater is proud of our longstanding partnership with D-Wave and this unprecedented innovation in quantum computing," said Thomas Sonderman, CEO of SkyWater. "This is an example of bleeding-edge technology taking place in a 200 mm fab – showcasing the importance of foundational node infrastructure here in the U.S. We believe that continued investment to modernize and expand domestic semiconductor manufacturing is essential to ensure that major breakthroughs like this one happen here – a national imperative for economic and security interests."
