AI总结:

研究开放量子系统在哈密顿扰动下的鲁棒均方稳定性,通过量子随机微分方程和威利量化形式分析扰动条件。

摘要:

本文研究动态变量满足规范对易关系的开放量子系统,其由量子随机微分方程驱动,受量子维纳过程影响。系统-场耦合算子是系统变量的线性函数。哈密顿量由名义二次函数和不确定扰动组成,扰动以威利量化形式表示。假设名义线性量子系统稳定,推导出保证扰动系统鲁棒均方稳定的充分条件。通过三角多项式形式的哈密顿扰动示例说明结果。

英文摘要:

This paper is concerned with open quantum systems whose dynamic variables satisfy canonical commutation relations and are governed by quantum stochastic differential equations. The latter are driven by quantum Wiener processes which represent external boson fields. The system-field coupling operators are linear functions of the system variables. The Hamiltonian consists of a nominal quadratic function of the system variables and an uncertain perturbation which is represented in a Weyl quantization form. Assuming that the nominal linear quantum system is stable, we develop sufficient conditions on the perturbation of the Hamiltonian which guarantee robust mean square stability of the perturbed system. Examples are given to illustrate these results for a class of Hamiltonian perturbations in the form of trigonometric polynomials of the system variables.
