Silicon qubits move a step closer to achieving error correction

Quantum bits (qubits) that use the quantum properties of electrons in silicon devices offer enormous potential for developing compact and robust quantum computers that take advantage of the existing silicon-microchip industry. But quantum operations are subject to error, and getting error rates low enough to make quantum silicon devices feasible remains a challenge. Three papers in this issue, by Xue et al.1, Noiri et al.2 and Mądzik et al.3, report demonstrations of qubit operations in silicon devices with fidelities above the threshold of one of the most popular quantum error-correcting codes. The results suggest that these devices could be a competitive platform for scalable quantum-information processing.
