Filtering noise through quantum control in high-dimensional systems (Conference Presentation)
Author(s): Michael Hush

Paper Abstract

Engineering-inspired filter functions are a powerful heuristic for the development of noise-robust quantum logic operations. We expand on existing single-qubit approaches and present a generalized, computationally efficient framework to calculate filter functions for operations performed on D-dimensional manifolds such as pairs of interacting qubits (including spectator levels), and qudits. We describe two applications of the generalized filter functions to superconducting qubits: 1. The design of robust controls for parametric gates. 2. Using entangled states as a probe for noise characterization.
