  1. To quantify robustness and infidelity of quantum controllers together, a statistical Monte Carlo robustness-infidelity measure (RIM) is presented with tunable structured perturbations.
  2. Analogously, a measure to describe the performance of algorithms to find high-fidelity, robust controllers is presented as algorithmic RIM (ARIM).
  3. Numerical results on energy landscape control of XX-Heisenberg chains indicate that not all high-fidelity controllers are also robust.
  4. There exists some benefit of incorporating certain noise in finding low RIM controllers.
