Two independent studies push semiconductor qubits towards practical scales
Two independent research groups have reported advances in semiconductor qubit fabrication or control that improve scalability, bringing silicon-based spin qubits closer to the qubit counts needed for error correction.

These results could lead to demonstration of a 10-qubit semiconductor device with two-qubit gate fidelities above 99% within two years, making semiconductor qubits competitive with other platforms for early error-correction experiments.
The two independent studies likely resolve key fabrication or control challenges, such as yield, variability, or crosstalk, which have historically limited spin qubit scaling. Recent industry momentum and improved materials suggest a clear path to integrating more qubits with high fidelity.
