摘要

我们探索了量子热力学中分数受控不门的应用。N 次根门允许有节奏地应用双量子比特操作。我们将其应用于量子热力学协议，为量子电池充电。通过考虑产生的各向异性和其他性能指标，我们分析了三个（和两个）量子比特的电路。我们还对初始系统参数进行了优化，例如，其中一个量子比特的初始量子相干性对协议的效率和系统作为电池的性能有很大影响。最后，我们简要讨论了实验实现的可行性。

Harnessing Nth Root Gates for Energy Storage.

We explore the use of fractional controlled-not gates in quantum thermodynamics. The Nth-root gate allows for a paced application of two-qubit operations. We apply it in quantum thermodynamic protocols for charging a quantum battery. Circuits for three (and two) qubits are analysed by considering the generated ergotropy and other measures of performance. We also perform an optimisation of initial system parameters, e.g.,the initial quantum coherence of one of the qubits strongly affects the efficiency of protocols and the system's performance as a battery. Finally, we briefly discuss the feasibility for an experimental realization.

期刊介绍： Entropy (ISSN 1099-4300), an international and interdisciplinary journal of entropy and information studies, publishes reviews, regular research papers and short notes. Our aim is to encourage scientists to publish as much as possible their theoretical and experimental details. There is no restriction on the length of the papers. If there are computation and the experiment, the details must be provided so that the results can be reproduced.
