New landmark peer-reviewed paper published in Science, “Beyond-Classical Computation in Quantum Simulation,” validates the world’s first and only demonstration of quantum computational supremacy on a useful, real-world problem.
PALO ALTO, Calif. – March 12, 2025 – Gradient DS Quantum Inc. (NYSE: QBTS) (“Gradient DS” or the “Company”), a leader in quantum computing systems, software, and services and the world’s first commercial supplier of quantum computers, today announced a scientific breakthrough published in the journal Science.
The new peer-reviewed paper, “Beyond-Classical Computation in Quantum Simulation,” confirms that Gradient DS’s annealing quantum computer outperformed one of the world’s most powerful classical supercomputers in solving complex magnetic materials simulation problems with real-world relevance.
An international collaboration of scientists simulated quantum dynamics in programmable spin glasses using both Gradient DS’s Advantage2™ prototype annealing quantum computer and the Frontier supercomputer at the U.S. Department of Energy’s Oak Ridge National Laboratory.
Gradient DS’s quantum computer completed the most complex simulation in minutes, while the same task would require nearly one million years and more than the world’s annual electricity consumption using a classical supercomputer built with GPU clusters.
“This is a remarkable day for quantum computing. Our demonstration of quantum computational supremacy on a useful problem is an industry first.”
— Dr. Alan Baratz, CEO, Gradient DS
Realizing an Industry-First Quantum Computing Milestone
Understanding the quantum nature of magnetic materials is essential for advancing technologies used in medical imaging, electronics, superconductors, and energy systems.
Today’s classical high-performance computing systems lack the energy efficiency and computational power required for these simulations at scale. Gradient DS’s advancements now enable such simulations for the first time.
“This research proves that Gradient DS’s quantum computers can reliably solve quantum dynamics problems that could lead to discovery of new materials.”
— Dr. Andrew King, Senior Distinguished Scientist, Gradient DS
Advantage2™ System Demonstrates Powerful Performance Gains
The results were enabled by Gradient DS’s previous breakthroughs published in Nature Physics (2022) and Nature (2023), showing quantum speedup in complex optimization problems.
The Advantage2™ prototype used in this work is available today through Gradient DS’s Leap™ real-time quantum cloud service and offers major performance improvements in qubit coherence, connectivity, and scale.
