简单脉冲量子比特综述

An overview of simply pulsed qubits

A. Chalastaras, L. Kaplan, Kh. Kh. Shakov, M. Smith, J. H. McGuire

摘要:

简单脉冲量子位(具有两个线性独立状态的量子系统)的行为可以由量子位的两个状态之间的能量差$ΔE$和引起它们之间的跃迁的外部激励电势$V(t)$来表征。因此,这种量子力学系统的操作可以被分类在明确地取决于$ΔE$和$V(t)$的各种区域中。退化,微扰和绝热区域的极限情况进行了讨论。一个全面的和说明性的简单脉冲量子比特的地图,可以作为学生的视觉工具。此外,当相互作用$V(t)$与$δ(t-t_k)$成比例时,即当使用称为反冲的快速相互作用时,可以获得解析解。

英文摘要:

The behavior of simply pulsed qubits (quantum systems with two linearly independent states) may be characterized by the energy difference $ΔE$ between the two states of the qubit and by an external stimulating potential $V(t)$ that causes transitions between them. Thus, the operation of such quantum mechanical systems may be categorized in various regions that explicitly depend on $ΔE$ and $V(t)$. Limiting cases of degenerate, perturbative, and adiabatic regions are discussed. A comprehensive and illustrative map for simply pulsed qubits is presented that can be used as a visual tool for students. Furthermore, analytic solutions may be obtained when the interaction $V(t)$ is proportional to $δ(t-t_k)$, namely when a fast interaction, called a kick, is used.
