Trace-Based Reconstruction of Quantum Circuit Dataflow in Surface Codes
From per-patch binary activity traces of surface-code lattice surgery, TraceQ reconstructs the two-qubit gate dependency DAG and detects embedded subroutines with 74-95% success and no false positives, but only on synthetic traces from the authors' own simulator.
