用两个不同的哈密顿量来模拟同一个物理

Simulating the same physics with two distinct Hamiltonians

Karol Gietka, Ayaka Usui, Jianqiao Deng, Thomas Busch

摘要:

我们开发了一个框架,并给出了一个例子的情况下,两个不同的哈密顿生活在同一个希尔伯特空间可以用来模拟相同的物理。作为模拟的一个例子,我们首先讨论了如何使用具有交错场的短程最近邻相互作用海森堡XXX模型来模拟无限程相互作用单轴扭转哈密顿量。在此基础上,我们展示了如何构建数字量子模拟器的替代版本。作为一个副产品,我们提出了一种方法来创建多体最大纠缠态仅使用短程最近邻相互作用。

英文摘要:

We develop a framework and give an example for situations where two distinct Hamiltonians living in the same Hilbert space can be used to simulate the same physics. As an example of an analog simulation, we first discuss how one can simulate an infinite-range-interaction one-axis twisting Hamiltonian using a short-range nearest-neighbor-interaction Heisenberg XXX model with a staggered field. Based on this, we show how one can build an alternative version of a digital quantum simulator. As a by-product, we present a method for creating many-body maximally entangled states using only short-range nearest-neighbor interactions.
