Quantum computing firm D-Wave has announced the general availability of its 1,200 qubit Advantage2 (Adv2) prototype.

First unveiled in 2022, the new Adv2 prototype features more than 1,200 qubits and 10,000 couplers and apparently demonstrates a 20x faster time-to-solution on hard optimization problems.

Compared to D-Wave’s previously released Advantage2 prototype, the machine has increased qubit connectivity from 15 to 20-way; scaled energy usage by more than 40 percent; and doubled qubit coherence time.

The Adv2 prototype is now available to customers who have the company’s Leap quantum cloud service subscription. New customers can sign up to the Leap service and receive up to one minute of free use of D-Wave’s quantum processing units (QPUs) and quantum hybrid solvers.

“Today marks an important milestone in our product delivery roadmap, as we open up access to the newest Advantage2 prototype for businesses, developers, and researchers across the globe,” said Mark W. Johnson, senior vice president of quantum technologies and systems products at D-Wave. “What we’re seeing with the Advantage2 prototype in terms of performance gains is remarkable, and we’re thrilled to make it available today to help customers start applying it to their complex problems now.”

D-Wave was the first commercial supplier of quantum computers and offers machines that utilize quantum annealing.

The company went public in August 2022 after a SPAC merger with DPCM Capital. However, in October 2023 the company faced a second potential delisting from the New York Stock Exchange (NYSE) over its low stock price. The company was given six months to bring its share price back above a $1 average closing share price over a 30-day period.

D-Wave’s stock price hit $1 on February 9, 2024, and sits at $1.35 at the time of publishing.
