At its Qubits 2021 Conference last October, D-Wave disclosed that it was developing its sixth generation quantum annealing processor codenamed Advantage2. This processor is expected to be released in 2023-2024 with about 7,000 qubits, improved performance, and an increased qubit connectivity to 20 from the previous 15. D-Wave has now named this 20-qubit topology as the Zephyr topology. As part of the development process, D-Wave has completed a 500+ qubit small-scale Advantage2 prototype that employs a new qubit design, significantly lower noise, and the 20-qubit connectivity. These improvements will make it easier to embed an annealing problem into the physical hardware for solution, decrease the number of qubits needed to solve problems, and provide more accurate results when the run programs run. What’s more, D-Wave has made this machine available for public use via their Leap Cloud Service so that users can get an early look at the new Zephyr topology and provide early feedback to D-Wave on the new architecture. Additional information about this Advantage2 prototype is available in a press release located here.
