D-Wave Quantum Inc. announced that the 1,200+ qubit Advantage2 prototype is now available via the company's Leap real-time quantum cloud service. Customers who have Leap service subscriptions can access the new Advantage2 prototype, and those new to the Leap service can sign up and get up to one minute of free use of the actual quantum processing units (QPUs) and quantum hybrid solvers, including the new Advantage2 prototype. Developed with a new lower-noise, multilayer superconducting integrated-circuit fabrication stack, the new Advantage2 prototype demonstrates significant performance gains on hard optimization problems and is expected to be particularly powerful for new use cases such as machine learning.

Announced earlier this year, the new Advantage2 prototype features 1,200+ qubits and 10,000+ couplers, double the number of qubits and couplers over the previously released Advantage2 prototype. Benchmarks demonstrate substantial advancements across a number of performance metrics compared to the Advantage quantum processing unit (QPU), including: Qubit connectivity: increased from 15 to 20-way connectivity to enable solutions to larger problems; Energy scale: increased by more than 40% to deliver higher-quality solutions; Qubit coherence time: doubled, which will drive faster time-to-s solution. The previously released Advantage2 experimental prototype has been heavily used by customers, solving more than three million problems since it was made available in 2022, a testament to the demand for D-Wave's evolving technology.
