希尔伯特空间平均法与绝热量子搜索

Hilbert Space Average Method and adiabatic quantum search

A. Perez

摘要:

我们讨论了与所谓的希尔伯特空间平均方法有关的一些方面,作为描述开放量子系统动力学的替代方法。首先,我们提出了一个推导的方法,它不利用代数所满足的运营商参与的动态,并扩展该方法的系统受一个哈密顿量,随时间变化。接下来,我们研究绝热量子搜索算法的性能与特定的环境模型。我们将我们的研究结果与文献中讨论的标准的有效性,上述方法用于类似的环境。

英文摘要:

We discuss some aspects related to the so-called Hilbert space Average Method, as an alternative to describe the dynamics of open quantum systems. First we present a derivation of the method which does not make use of the algebra satisfied by the operators involved in the dynamics, and extend the method to systems subject to a Hamiltonian that changes with time. Next we examine the performance of the adiabatic quantum search algorithm with a particular model for the environment. We relate our results to the criteria discussed in the literature for the validity of the above-mentioned method for similar environments.
