Quantum Computing Inc. (QCi) has announced Dirac-3S, the next generation of its Dirac-3 quantum optimization machine. The company says the new system scales to nearly 10,000 variables, marking a substantial step up from its predecessor in handling large optimization problems.
The announcement, made Oct. 1, 2026, from Hoboken, N.J., describes QCi as a vertically integrated quantum systems company pioneering photonics and semiconductor manufacturing. The release positions Dirac-3S as a continuation of the Dirac-3 line, though it does not specify exact performance gains beyond the increased variable count.
As a quantum optimization machine, Dirac-3S is designed for optimization tasks rather than general-purpose quantum computing. QCi's emphasis on photonics-based hardware differentiates its approach from other quantum technologies, but the announcement offers no independent benchmarks or customer results to validate the scaling claim.
