Extended Data Fig. 2

a, SQ RB for all four qubits. b, TQ RB results for zone 1. c, TQ RB results for zone 2. d, An estimated error budget for a single TQ gate operation. e, Correlation parameters for simultaneous TQ RB. Each square represents a value of δi,j with the numbers being scaled by 10−4. All are within one standard deviation of zero. f, Addressability error estimates for simultaneous RB. The quantities \({\alpha }_{z}^{{\rm{both}}}\) and γz refer to simultaneous RB decay rates and their deviation from individual RB decay rates, as described in the text.
