Quantum error correction goes well beyond breakeven

A team of researchers conducted a demonstration of quantum error correction, showing significant reductions in error rates as the number of qubits increased. The experiment used a combination of 10 qubits and a surface code to achieve the results, with 22 errors corrected in a single run. The team's findings suggest that quantum error correction can be scaled up to larger numbers of qubits, bringing the technology closer to practical applications.
