TL;DR
Diraq's qubits chips hold up 99+% accuracy when made in an industrial CMOS foundry.
The Nature article "Industry-compatible silicon spin-qubit unit cells exceeding 99% fidelity" describes an industrial process used by the Australian company "Diraq" to manufacture small (2 qubit) evaluation devices using CMOS technology.

The results show that the process will likely support much larger functional qubit devices.

Some articles (such as this one from Science Daily) also claim that the study demonstrates the devices will meet DARPA's Quantum Benchmark Initiative (QBI) goals, but I cannot find any DARPA document describing any such goals.
