Robustness of open quantum systems at strong coupling

开放量子系统理论描述了量子系统的行为，这些量子系统不是孤立的，而是与周围环境的自由度相联系。特别是，了解开放量子系统对于开发未来的量子技术具有很强的抗噪声能力至关重要。本项目旨在了解在强库相互作用的影响下绝热量子计算协议的鲁棒性。这种形式的量子计算将信息编码在量子系统的基态内，然后缓慢地操纵以执行所需的操作。利用所开发的理论，我们将研究热环境影响这种绝热协议的方式，目的是在强环境相互作用的情况下优化它们。

Open quantum systems theory describes the behaviour of quantum systems that are not isolated, but instead in contact with their surrounding environmental degrees of freedom. In particular, understanding open quantum systems is crucial to the development of future quantum technologies that are robust against noise.This project seeks to understand the robustness of protocols for adiabatic quantum computation under the influence of strong reservoir interactions. This form of quantum computation encodes information within the ground state of a quantum system, which is then slowly manipulated to perform a desired operation. Using the theory developed, we will study ways in which thermal environments can impact such adiabatic protocols, with the aim of optimising them in the presence of strong environmental interactions.
