冷囚禁离子系统的压缩控制动力学

Governing dynamics by squeezing in a system of cold trapped ions

G. Ramon, C. Brif, A. Mann

摘要:

本文研究了激光冷却离子在线性谐振子阱中的压缩交换现象。当内部子系统和运动子系统处于适当的压缩(智能)态时,发现了量子噪声减少(压缩)和动力学演化之间的一个有趣的关系。具体地说,系统的演化完全取决于光谱压缩和运动压缩的相对强度,包括当初始压缩参数相等时相互作用完全取消的现象。

英文摘要:

We consider a system of laser-cooled ions in a linear harmonic trap and study the phenomenon of squeezing exchange between their internal and motional degrees of freedom. An interesting relation between the quantum noise reduction (squeezing) and the dynamical evolution is found when the internal and motional subsystems are prepared in properly squeezed (intelligent) states. Specifically, the evolution of the system is fully governed by the relative strengths of spectroscopic and motional squeezing, including the phenomenon of total cancellation of the interaction when the initial squeezing parameters are equal.
