Andre G. Campos, Renan Cabrera, Herschel A. Rabitz, Denys I. Bondar

摘要:

一个简单的框架狄拉克旋量的参数化容许量子动力学,并解析构造电磁场,服从麦克斯韦方程组,产生所需的演变。特别是,我们展示了如何实现无色散旋转和平移的波包。此外,这种形式主义可以处理电磁之外的控制交互。这项工作揭示了狄拉克方程在控制应用中意想不到的灵活性,这可能为量子技术开辟新的前景。

英文摘要:

A simple framework for Dirac spinors is developed that parametrizes admissible quantum dynamics and also analytically constructs electromagnetic fields, obeying Maxwell's equations, which yield a desired evolution. In particular, we show how to achieve dispersionless rotation and translation of wave packets. Additionally, this formalism can handle control interactions beyond electromagnetic. This work reveals unexpected flexibility of the Dirac equation for control applications, which may open new prospects for quantum technologies.
