0 reviewsAmong the many types of qubit presently being investigated for a future quantum computer, silicon spin qubits with millions of qubits on a single chip are uniquely positioned to enable quantum computing. However, it has not been clear whether the outstanding high-fdelity operations and long coherence times shown by silicon spin qubits fabricated in academic settings1–8 can be reliably reproduced when the qubits are manufactured in a semiconductor foundry9–11. Here we show precise qubit operation of silicon two-qubit devices made with standard semiconductor tooling in a 300-mm foundry environment. Of the key metrics, single- and two-qubit control fdelities exceed 99% for all four devices, and the state preparation and measurement fdelities reach up to 99.9%, as evidenced by gate set tomography. We report spin lifetime and coherence up to T1 = 9.5 s, T*= 40.6 µs 2Hahn . We determine 2 and T = 1.9 ms that residual nuclear spin-carrying isotopes contribute substantially to operational errors, identifying further isotopic purifcation as a clear pathway to even higher performance.
