Silicon qubits reach the standard for quantum error correction

Good news! This could be an important milestone!

"An important threshold in quantum error correction has been reached using silicon-based qubits. The feat was performed by three independent research groups, who used the spins of individual electrons or nuclei to create quantum logic gates, which carried out operations with over 99% fidelity.
One team was a collaboration between researchers at the Japan’s RIKEN Centre for Emergent Matter Science and QuTech in the Netherlands. The second was an international team led by researchers at the University of New South Wales (UNSW) in Australia and the third team was based solely at QuTech. ..."
