Surface and Interface Engineering for Superconducting Quantum Circuits (2023–2026)

Abstract:
The limiting factor for current quantum computers is a process called decoherence. This project aims to identify new strategies to reduce decoherence in quantum computer components using an interdisciplinary approach based on quantum physics, materials science, and engineering. This project involves investigating the effect of atomically sharp interfaces on decoherence and using capping layers to control and/or inhibit oxide growth that reduce the contribution of interfaces to decoherence. Expected outcomes of this project include development of solutions to fabricate long-lived superconducting qubits benefiting superconducting quantum technologies and making a significant step towards realisation of a practical quantum computer.
