Fidelity-Based Robustness Margins for Finite-Time Quantum Control
S. P. O'Neil, F. C. Langbein, C. A. Weidner +2
We develop a structure-specific fidelity-threshold robustness margin for finite-dimensional closed quantum systems under piecewise-constant coherent control. A scalar physical para…
Energy Landscape Shaping for Robust Control of Atoms in Optical Lattices
C. A. Weidner, S. P. O'Neil, E. A. Jonckheere +2
Robust quantum control is crucial for realizing practical quantum technologies. Energy landscape shaping offers an alternative to conventional dynamic control, providing theoretica…
Robust Quantum Control in Closed and Open Systems: Theory and Practice
C. A. Weidner, E. A. Reed, J. Monroe +6
Robust control of quantum systems is an increasingly relevant field of study amidst the second quantum revolution, but there remains a gap between taming quantum physics and robust…
Robustness of Dynamic Quantum Control: Differential Sensitivity Bound
S. P. O'Neil, C. A. Weidner, E. A. Jonckheere +2
Dynamic control via optimized, piecewise-constant pulses is a common paradigm for open-loop control to implement quantum gates. While numerous methods exist for the synthesis of su…
