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的。特别是，理解开放量子系统对于未来抗噪声量子技术的发展至关重要。该项目旨在了解在强储层相互作用影响下绝热量子计算协议的鲁棒性。这种形式的量子计算在量子系统的基态内对信息进行编码，然后慢慢地操纵它来执行所需的操作。利用开发的理论，我们将研究热环境如何影响这种绝热协议，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.
