Abstract
The goal of this thesis is the design and development of the QuTech Central Controller, a system conceived to serve as the hardware/software interface of a quantum computer. This system represents an evolution of the QuMA microarchitecture to control a Surface-17 superconducting quantum processor, even though several architectural mechanisms are used to ensure the compatibility of the design with different quantum hardware technologies. In addition to an expansion of the control microarchitecture, the QuTech Central Controller represents an evolution of the overall system architecture, making use of a different hardware infrastructure to overcome previous scalability limitations.
The main contributions of this thesis are a proposed centralized microarchitecture capable of controlling up to 17 qubits, the implementation of this microarchitecture in a device called the QuTech Central Controller and its testing in dynamic quantum information processing experiments with superconducting qubits.
