Chip Used in D-Wave’s Prototype Advantage2 Quantum Annealer

We described earlier this month D-Wave’s Progress and Future Roadmap and that article mentioned that they had developed a 1200+ qubit prototype of their Advantage2 architecture. D-Wave indicates that the Advantage2 architecture has several significant improvements over their original Advantage architecture including an increase in qubit connectivity from 15 to 20, a multilayer superconducting integrated-circuit fabrication stack, a doubling of qubit coherence time, faster time to solution, and a 40% higher energy scale to deliver higher quality solutions. Further, they indicate that even though this prototype features fewer qubits than their current 5000 qubit Advantage2, it can provide better performance for many problems. Although this prototype machine is just a stepping stone to their ultimate goal of having a 7000 qubit Advantage2, the company has decided to make the machine available to their end users via the Leap Quantum Cloud Service so that the end users can take early advantage of its increased capabilities. The company has released a press release announcing the availability of this machine which you can access here.
