$1 per qubit is Diraq’s target for making quantum computing economically scalable, with the company arguing cost—not just useful machines—will determine whether the technology reaches broad adoption.
1 kelvin operating temperatures let Diraq use less demanding helium-based cooling than superconducting rivals running at 10 to 20 millikelvin, lowering what is currently the biggest system expense.
300 millimeter foundry runs already produce hundreds of chips per wafer, but Diraq says it uses only a few today, so it has not yet captured the full CMOS scaling benefits that could spread fixed cryogenic costs across millions of qubits.
By the early 2030s, Diraq expects cryogenics to become a relatively fixed cost and the main expense to shift to the classical compute stack—decoders, GPU clusters and cryogenic electronics—with the chip itself falling below 1 cent per qubit.
