Independent, extensible control of same-frequency superconducting qubits by selective broadcasting (npj Quantum Information (2016) 2, 16029, 10.1038/npjqi.2016.29)

Abstract

The original version of this Article contained an error in one of the calculations within the Results section. Although the authors note that this leakage rate is per Clifford, they actually quote the value per nanosecond: ‘We extract per Clifford leakage rates κ of 4.1(2) × 10− 6 (QT) and 1.3(4) × 10− 6 (QB) by fitting the following simple model to the data’. Now reads: ‘We extract per Clifford leakage rates κ of 1.4(2) × 10− 4 (QT) and 3.9(4) × 10− 5 (QB ) by fitting the following simple model to the data’. This error has now been corrected in the PDF and HTML versions of the Article.
