Robust geometric gate against crosstalk

Designed simultaneous randomized benchmarking sequences to measure crosstalk resilience.

Problem

Superconducting qubits suffer crosstalk during gate execution, degrading fidelity.

Approach

Developed geometric-gate pulses and benchmarking routines on IBM Quantum hardware to characterize robustness.

Outcome

Benchmarked crosstalk-robust gates (Feb 2022–Feb 2023) feeding into the NANO KOREA 2022 presentation.
