Separating Ideal-Circuit Structure from Hardware-Dependent Deviations in a Fixed 35-Qubit Diagnostic Circuit on IBM Heron Processors

H. Billah and M.M.H. Sarker contributed equally to this work. Interpreting a fixed quantum circuit's output as evidence of a hardware effect requires ruling out two things usually conflated with it: finite-sample fluctuation, and structure already present in the circuit's own noi...
