What does quantum advantage actually mean? How do you prove a quantum computer can outperform the world’s most powerful supercomputers? And why is its energy efficiency arriving at such an important time for the world?
In this episode of Quantum Matters, host Murray Thom sits down with Dr. Andrew King, Senior Distinguished Scientist at D-Wave, to discuss the company’s landmark peer-reviewed research demonstrating quantum computational advantage on a
problem relevant to materials discovery.
Together, they unpack the result behind the headlines, including a calculation completed in minutes on a quantum processor that could take classical supercomputers nearly a million years. They explore what it took to validate that claim, why energy efficiency is becoming a critical part of the quantum computing story, and how these advances could impact materials science, blockchain, and AI.
Join us for an inside look at one of the most significant milestones in quantum computing and what it could mean for the future of computation.
