Error mitigation is perhaps the biggest challenge and barrier to implementing practical quantum computing in the era of noisy intermediate scale quantum (NISQ) computers. Last week, Google reported promising use of so-called “stabilizer code” on its 54-qubit Sycamore quantum processor to suppress errors. The recent work, published in Nature Communications, reduced the number of errors requiring correction 100-fold per round, reported Google researchers. There’s a good account,… Source link
