工程开放系统与原子离子量子模拟

Engineered Open Systems and Quantum Simulations with Atoms and Ions

M. Müller, S. Diehl, G. Pupillo, P. Zoller

摘要:

在过去的几十年里,原子、分子和光学(AMO)物理学的巨大实验进展使我们能够分离出单个、几个甚至多个微观粒子的集合体,并以一定的精度操纵它们的量子特性,这在几年前还是不可想象的。这套多功能的工具使得在各种物理平台上的多体哈密顿工程的成熟概念得以发展。然而,这些可用的工具也可以用来将哈密顿工程的场景扩展到更一般的刘维尔环境,除了相干动力学之外,还包括多体量子系统中的受控耗散。在这里,我们回顾了最近的理论和实验进展,在不同的方向沿着这些路线,特别关注的物理实现与原子和离子的系统。这包括数字量子模拟在一个一般的开放系统设置,以及工程和理解远离热力学平衡的系统的新类别。

英文摘要:

The enormous experimental progress in atomic, molecular and optical (AMO) physics during the last decades allows us nowadays to isolate single, a few or even many-body ensembles of microscopic particles, and to manipulate their quantum properties at a level of precision, which still seemed unthinkable some years ago. This versatile set of tools has enabled the development of the well-established concept of engineering of many-body Hamiltonians in various physical platforms. These available tools, however, can also be harnessed to extend the scenario of Hamiltonian engineering to a more general Liouvillian setting, which in addition to coherent dynamics also includes controlled dissipation in many-body quantum systems. Here, we review recent theoretical and experimental progress in different directions along these lines, with a particular focus on physical realizations with systems of atoms and ions. This comprises digital quantum simulations in a general open system setting, as well as engineering and understanding new classes of systems far away from thermodynamic equilibrium.
