D-Wave Quantum Inc. announced new and renewed commercial customer engagements along with product updates for its annealing and gate model quantum computing solutions at the company's annual global Qubits 2023 user conference. Product Updates Reflect New Milestones for Both Annealing and Gate Model Platforms: In support of the Clarity product roadmap announced at the last Qubits conference in 2021, D-Wave shared a number of updates, furthering its consistent track record of delivering ground-breaking technology innovations and powerful, usable quantum systems, software, and tools to market. D-Wave shared progress toward its next generation Advantage2™ annealing quantum computing system, which is expected to feature 7,000+ qubits and 20-way connectivity, and will be implemented in a new lower-noise fabrication stack, all to enable customers to solve more complex problems with greater precision, including: Improvements in qubit coherence: A significant 4x reduction in noise was demonstrated for qubits within prototype processors fabricated from a newly developed lower noise fabrication process.

This means higher coherence qubits and is expected to lead to additional performance gains for the Advantage2 quantum system, beyond those already achieved and released in the Advantage2 experimental prototype that was made available in the Leap TM quantum cloud service in June 2022. Launch of new problem visualizer: TheOceanTM SDK and problem visualizer are now updated to reflect the higher Advantage2 connectivity (20-way), highlighting more compact embedding that enables larger, more complex problems and better solutions Demonstrating continued advancement of its software solutions, D-Wave also showcased several recent enhancements to its constrained quadratic model (CQM) hybrid solver in Leap, including: Continuous variables: enabling better representation of constrained problems – such as production capacity, available funds, and asset tracking – by using continuous variables and thus expanding the scope of quantum solutions into the Mixed Integer Programming (MIP) space. Weighted constraints: allowing quantum developers to more easily and accurately model problems where it is not possible to satisfy all constraints through classical computing logic.

Pre-solve techniques: reducing the size of problems and allowing for larger models to be submitted to the hybrid solver by removing unnecessary variables and constraints to achieve a cleaner data set. Also at Qubits, D-Wave shared continued progress in the development of its gate model computing system, revealing several milestones, including: Scalable qubit designed and readout method validated: D-Wave is currently benchmarking 1- and 2-qubit fluxonium qubit circuits manufactured in its fabrication process and has validated a new scalable readout method for gate model architecture. In addition, D-Wave has completed a first iteration of a logical qubit design, which leverages new scalable control and readout technologies.

Gate model simulator launched in Ocean: D-Wave has introduced a new gate model simulator in the Ocean suite of open-source tools, enabling developers to construct quantum circuits, create and add quantum gates to any circuit, and simulate circuits on its performant state-vector simulator.
