D-Wave Quantum Inc. (NYSE: QBTS), a leader in quantum computing systems and the world's first commercial supplier of quantum computers, has announced a significant breakthrough in gate-model quantum computing. The company has successfully demonstrated scalable on-chip cryogenic control of qubits, an industry-first milestone that advances the development of commercially viable gate-model quantum computers by reducing the wiring required to control large numbers of qubits without degrading qubit fidelity.
This 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's 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 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 both 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.

This breakthrough is important because it addresses one of the key challenges in scaling gate-model quantum computers: the wiring bottleneck. Traditional approaches require thousands of wires to control individual qubits, which becomes impractical as the number of qubits increases. By leveraging on-chip cryogenic control, D-Wave has demonstrated a path to significantly reduce wiring complexity, which is a critical step toward building larger, more powerful quantum computers that can solve real-world problems in optimization, artificial intelligence, and research.
D-Wave's achievement also highlights the company's unique position as a dual-platform quantum computing provider, offering both annealing and gate-model systems. This allows customers to choose the most suitable technology for their specific computational challenges. With over 200 million problems submitted to its quantum systems to date, D-Wave continues to demonstrate its leadership in the quantum computing industry.
