Robustness Analysis for Quantum Systems Controlled by Continuous-Time Pulses
Sean Patrick O'Neil, Edmond Jonckheere, Sophie Schirmer
Differential sensitivity techniques originally developed to study the robustness of energy landscape controllers are generalized to the important case of closed quantum systems sub…

Geometric Interpretation of Sensitivity to Structured Uncertainties in Spintronic Networks
Sean Patrick O'Neil, Edmond Jonckheere, Sophie Schirmer
We present a geometric model of the differential sensitivity of the fidelity error for state transfer in a spintronic network based on the relationship between a set of matrix oper…

Topological Discrimination of Steep to Supersteep Gap as Evidence of Tunneling in Adiabatic Quantum Processes
Edmond Jonckheere
It is shown that the gap that limits the speed of a quantum annealing process can take three salient morphologies: (i) the supersteep gap where both the ground and the first excite…
