I’m not sure if that’s happening here, but Quantum Art, the trapped-ion quantum computing startup with a roadmap to a massive 1,000-qubit quantum computer, just extended its $100 million series A with an additional $40 million in funding.That brings the company’s lifetime funding to roughly $164 million, most of it in this big A round. Bedford Ridge Capital, which led the original $100 million tranche announced in December, led the extension as well. New investors joining the cap table include Hudson Bay Capital, Poalim Equity, LIP Ventures, Wolverine Global Ventures and IDA Ventures.Quantum Art says the extension was driven by investor demand, and it lands just as the company is making its first real move from R&D into commercial deployment.

That’s the same playbook IBM Quantum, IonQ, IQM Quantum Computers and Quantinuum have been refining for years, but it’s a significant step for the relatively...
