非均匀磁场作为量子速度极限的助推器：更快的量子信息处理
Non-uniform magnetic field as a booster for quantum speed limit: faster quantum information processing
摘要：
本文研究了电子在非均匀磁场中的量子速度极限。我们表明，QSL增加到一个大的值，但在制度的因果关系，通过选择一个适当的变化磁场。我们还探讨了量子稳定性对电子自旋的依赖性，发现在相对论区域，自旋向下的电子的量子稳定性更高。这对于实现量子信息的更快传输速度是有用的。此外，我们使用Bremermann-Bekenstein绑定找到一个临界磁场，桥梁之间的差距，非相对论和相对论的治疗，并涉及到物质的稳定性。建立了一个分析框架。我们还提供了一个合理的实验设计，以补充我们的理论。
英文摘要：
We probe the quantum speed limit (QSL) of an electron when it is trapped in a non-uniform magnetic field. We show that the QSL increases to a large value, but within the regime of causality, by choosing a proper variation in magnetic fields. We also probe the dependence of QSL on spin of electron and find that it is higher for spin-down electron in the relativistic regime. This can be useful in achieving a faster speed of transmission of quantum information. Further, we use the Bremermann--Bekenstein bound to find a critical magnetic field that bridges the gap between non-relativistic and relativistic treatments and relates to the stability of matter. An analytical framework is developed. We also provide a plausible experimental design to supplement our theory.
