Design and fabrication of transmon qubits

Despite the monumental advances made in classical computing technology over the past decades, computationally expensive tasks are still presenting daunting challenges to researchers and industry. Quantum computing has the potential to revolutionize many facets of information technologies by pushing the frontiers in various fields ranging from machine learning to cryptography. This research project aims at designing and fabricating the fundamental building block of a quantum computer, a qubit, using industry standard nano-fabrication techniques. Among the many architecture candidates, we have chosen one based on Circuit Quantum Electrodynamics, arguably one of the most promising technologies. This project focuses on a specific qubit design named transmon qubit. First, a computer assisted design (CAD) will be made using Anyon Systems Inc. in-house software tools. Second, a fabrication recipe will be elaborated and tested in the University facilities. Third, the proper functioning of the device will be validated using state-of-the-art experiments.
