An important threshold in quantum error correction has been reached using silicon-based qubits. Three different research groups, Japan’s RIKEN Centre for Emergent Matter Science, the University of New South Wales, and QuTech.  This is important because, so far, our quantum computers are super delicate. Silicon is the best material available when it comes to  scalability.  This successful testing of the creation of two-qubit logic gates above the 99% error correction gates means a large-scale quantum computer may be realized sooner than we thought!
