Designing dynamically corrected gates robust to multiple noise sources using geometric space curves: Part 2

Quantum processors typically suffer from multiple noise sources that degrade the quality of gates. In this talk, I will present a general technique to design control pulses that simultaneously suppress noise in both qubit energy levels and control fields. This is facilitated through a reverse engineering approach known as the space curve quantum control (SCQC) formalism in which closed curves in Euclidean space map to robust control fields. Constraints on these curves give necessary and sufficient conditions for robust evolution. Several methods for how to build such curves will be presented.
