D-Wave Quantum Inc. (NYSE: QBTS), a leader in quantum computing systems and the world's first commercial supplier of quantum computers, announced a milestone in gate-model quantum computing: the first demonstration of scalable, on-chip cryogenic control of gate-model qubits. This advancement addresses a critical challenge in building large-scale gate-model quantum processors by significantly reducing the number of wires needed to control qubits without degrading performance.
The on-chip cryogenic control technology was originally developed by D-Wave for its commercial annealing quantum processing units (QPUs). In D-Wave's annealing systems, multiplexed digital-to-analog converters control tens of thousands of qubits and couplers using only 200 bias wires. The company has now shown that the same approach can be applied to its gate-model architectures, potentially enabling large-scale, practical gate-model QPUs that require far less wiring complexity while maintaining qubit fidelity.
D-Wave is the world's first and only dual-platform quantum computing company, offering both annealing and gate-model systems to address a wide range of computational problems. The company's quantum computers feature QPUs with sub-second response times and are available on-premises or via its quantum cloud service, which boasts 99.9% availability. More than 100 organizations have used D-Wave's systems to solve over 200 million problems spanning optimization, artificial intelligence, and research.
