Abstract:

This project aimed to address the most significant challenge facing the development of large-scale quantum computers suppressing hardware error. Through this work we focused on the realization of a robust, high-fidelity Quantum Control Toolkit that is fully transportable between different quantum computing technology platforms. The techniques encapsulated herein were designed to provide qubit robustness to decoherence during memory dynamical decoupling DD, and increase the fidelity of qubit operations undertaken in the presence of random environmental noise and control imperfections dynamically corrected gates DCGs, and composite pulses CPs. This project has seen the demonstration of significant hardware-based improvements in quantum control fidelity along with the full experimental validation of an engineering-inspired filter-transfer function framework for quantum control.
