论文摘要
通过将依赖时间的变分原理（TDVP）应用于schrödinger方程，研究了捕获离子运动的挤压相干状态（CSS）的演变。该方法是在保罗和组合陷阱的情况下应用的，为此，源自经典的哈密顿量和运动方程。因此，CS提供了一个自然框架：（a）用于超抑制测量的被困离子的工程师量子相关状态，（b）探索负责脱干的机制，以及（c）研究量子型经典过渡。
The evolution of squeezed coherent states (CSs) of motion for trapped ions is investigated by applying the time dependent variational principle (TDVP) for the Schrödinger equation. The method is applied in case of Paul and combined traps, for which the classical Hamiltonian and equations of motion are derived. Hence, CS provide a natural framework to: (a) engineer quantum correlated states for trapped ions intended for ultraprecise measurements, (b) explore the mechanisms responsible for decoherence, and (c) investigate the quantum-classical transition.
