D-Wave Quantum Inc. (NYSE: QBTS), a leader in quantum computing systems and the world’s first commercial supplier of quantum computers, announced a breakthrough in gate-model quantum computing with the successful demonstration of scalable on-chip cryogenic control of qubits. This industry-first milestone advances the development of commercially viable gate-model quantum computers by significantly reducing the wiring required to control large numbers of qubits without degrading qubit fidelity.
The achievement validates that the on-chip cryogenic control technology D-Wave developed for its commercial annealing quantum processing units (QPUs) can also be applied to its gate-model architectures. In D-Wave annealing systems, the control technology uses multiplexed digital-to-analog converters to control tens of thousands of qubits and couplers with just 200 bias wires. The same control technology can also reduce gate-model wiring complexity while maintaining qubit fidelity, enabling large-scale, practical gate-model QPUs.
D-Wave is the world’s first and only dual-platform quantum computing company, building and delivering annealing and gate-model quantum computing technology to address customers’ full set of complex computational problems. The company’s quantum computers feature QPUs with sub-second response times and can be deployed on-premises or accessed through its quantum cloud service, which offers 99.9% availability and uptime. Over 100 organizations trust D-Wave with their toughest computational challenges, and more than 200 million problems have been submitted to its quantum systems to date.
This breakthrough is significant because wiring complexity is a major bottleneck in scaling gate-model quantum computers. By applying cryogenic control technology already proven in annealing systems, D-Wave demonstrates a path to building gate-model QPUs with thousands of qubits, moving closer to practical quantum advantage. The approach could accelerate the timeline for commercial gate-model quantum computers, which are expected to tackle problems in optimization, artificial intelligence, and research beyond the reach of classical computers.
