D-Wave Quantum agrees to acquire Quantum Circuits for $550 million to boost gate-model development

D-Wave Quantum announced Wednesday that it has struck a deal to purchase Quantum Circuits for $550 million, as the annealing-centric quantum computing company continues its push to bolster its gate-model capabilities.

The company said that $300 million will be paid in D-Wave stock, with the remainder in cash.

D-Wave is the major player in annealing quantum computing, an approach that solves more specialized optimization problems. Gate-based quantum computers, which aim to address even more complex and broad queries, are the dominant approach being pursued by publicly traded quantum computing firms. Gate model developers have also tended to get more interest from government agencies, as their technology is seen as the ultimate end point for quantum computing and therefore more worthy of support.

“By combining the world’s leading annealing quantum computing company with the world’s leading developer of error-corrected gate-model technology, D-Wave will dramatically accelerate the projected time to a scaled, error-corrected gate-model quantum computer alongside and complementary to its commercial annealing quantum systems,” per the press release. “Combining these technologies is expected to facilitate an accelerated commercial gate-model product roadmap that D-Wave believes will enable it to be the first to deliver fully error-corrected, scaled gate-model quantum computing”

Thanks to this acquisition, D-Wave plans to deliver an initial dual-rail gate-model system in 2026.

During the conference call that followed the release of Q3 earnings in November, CEO Dr. Alan Baratz highlighted gate-model development as a priority for D-Wave.

“Up until now, our investment in gate has been light, mostly because we haven’t had the funds to be able to grow that investment all that much. Now with the roughly $830 million in the bank, we have the resources to be able to invest more in that program, both internal investment and through acquisition to accelerate the program,” he told Sherwood News.

“We have one customer who has said, ‘When you have a gate-model system, I want it.’”

This news comes on the heels of the firm’s announcement on Tuesday that it’s solved a key problem when it comes to scaling superconducting gate-model quantum computers: how to keep qubits in the same place without producing too much heat.
