Google Makes Progress on Scaling Quantum Error Correction | NextBigFuture.com

Google has a quantum computing goal of encoding a logical qubit on 1000 physical ones with an error rate of 0.0001% and they have achieved a 3% error rate using 17 qubits. The scaling or error reduction must be 20 times better. Using a 72-qubit chip, the Google team encoded a single logical qubit in ... Read more
