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的工作人员阅读项目细节将试图确定我们的研究领域的项目适合（它可能是一个以上）。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：项目试图解决的研究问题/项目的目标;将采取的方法来回答这些问题（学生实际上在做什么）;研究的新工程和/或物理科学内容如果你认为你知道EPSRC的哪些研究领域与这个项目相关，那么把这个包括进去会很有帮助。项目说明的编写应使受过教育的非专业人员能够理解，任何缩略语都应加以界定。该项目旨在评估开放量子系统中热力学控制协议中随机噪声的影响。我们将探讨如何强大的控制协议，如绝热性的捷径，可以在其应用中的缺陷，例如通过控制信号的幅度和相位的不可控波动所产生的。我们将使用主方程技术和随机解开模型的热机和制冷噪声控制下的量子热力学循环。全计数统计技术将被扩展到噪声控制的情况下，计算热力学指标，如循环功率，效率，和它们的方差。我们将应用我们的研究结果，提出新的量子控制协议，以优化这些热力学指标存在不完美的控制限制。
