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.

当前量子计算机的限制因素是一个称为退相干的过程。该项目旨在确定新的策略，以减少量子计算机组件中的退相干，使用基于量子物理学，材料科学和工程的跨学科方法。该项目涉及调查 原子级尖锐界面对退相干的影响，以及使用覆盖层来控制和/或抑制氧化物生长，从而减少界面对退相干的贡献。该项目的预期成果包括开发制造长寿命超导量子比特的解决方案，使超导量子技术受益，并朝着实现实用量子计算机迈出重要一步。
