EPSRC staff reading the project details will be trying to determine which of our research areas the project fits into (it could be more than one). To help them do this, project details provided should be as specific as possible and clearly describe: the research questions the project is trying to address/the objectives of the project; the approach that will be taken to answer these questions (what the student will actually be doing); the novel engineering and/or physical sciences content of the research (the science that places it within EPSRC's remit).If you think you know which EPSRC research areas are relevant to the project, it would be helpful to include this. The project description should be written so as to be understandable by an educated lay-person and any acronyms should be defined. This project aims to assess the impact of random noise within thermodynamic control protocols in open quantum systems. We will explore how robust control protocols, such as shortcuts to adiabaticity, can be made to imperfections in their application, arising for example through uncontrollable fluctuations in the amplitude and phase of the control signals. We will use both master equation techniques and stochastic unravelings to model quantum thermodynamic cycles for both heat engines and refrigeration under noisy control. Full counting statistics techniques will be extended to noisy control situations to calculate thermodynamic metrics such as cycle powers, efficiencies, and their variances. We will apply our findings to suggest novel quantum control protocols to optimise these thermodynamic metrics in the presence of imperfect control restrictions.

EPSRC阅读项目详细信息的工作人员将尝试确定该项目适合的研究领域（可能不止一个）。为了帮助他们做到这一点，提供的项目细节应尽可能具体并清楚地描述：该项目试图解决项目目标的研究问题； 要回答这些问题的方法（学生实际上将在做什么）； 研究的新型工程和/或物理科学内容（将其置于EPSRC的职位中的科学）。如果您认为您知道哪些EPSRC研究领域与该项目相关，那么将其包括在内会很有帮助。应该编写项目描述，以便由受过教育的外行人可以理解，并应定义任何首字母缩写词。该项目旨在评估在开放量子系统中热力学控制方案中随机噪声的影响。我们将探讨如何使其应用程序的不完美之类的稳健控制方案（例如与绝热性的快捷方式），例如，通过在控制信号的幅度和相位中无法控制的波动而产生。我们将同时使用主方程技术和随机分解，以模拟噪音控制下的热发动机和制冷的量子热力学循环。完整的计数统计技术将扩展到嘈杂的控制情况，以计算热力学指标，例如周期功率，效率及其方差。我们将应用我们的发现来建议新的量子控制方案，以在存在不完美的控制限制的情况下优化这些热力学指标。
