Investigating how adversarial pulses exploit interqubit coupling to induce logical errors in shared superconducting quantum processors. My work combines pulse-level simulation, quantum process tomography, and isometry-based circuit extraction to reconstruct induced error channels and characterize an asymmetric crosstalk attack mechanism. I also develop methods for quantum characterization, verification, and validation (QCVV) using residual Pauli transfer matrices, including calibrated detection of weak coherent two-qubit crosstalk versus local calibration drift at matched average gate infidelity.
- Pulse-level simulation of crosstalk attacks and pulse-to-circuit characterization of their induced error channels [C4, C5].
- Multiqubit pulse calibration, including Rabi calibration and echoed cross-resonance gates, alongside open-system dynamics and process characterization.
