囚禁离子自旋模型的数模量子模拟

Digital-Analog Quantum Simulation of Spin Models in Trapped Ions

I. Arrazola, J. S. Pedernales, L. Lamata, E. Solano

摘要:

我们提出了一种方法来模拟自旋模型中被困离子使用的数字模拟的方法,包括在一个合适的门分解方面的模拟块和数字步骤。通过这种方式,我们证明了增强的各种自旋模型的量子动力学可以用比全数字方法少得多的门来实现。通常情况下,模拟块是建立多部动力学提供的模拟模型的复杂性,而数字步骤是本地操作带来的多功能性。最后,我们描述了一个可能的实验实现中的捕获离子技术。

英文摘要:

We propose a method to simulate spin models in trapped ions using a digital-analog approach, consisting in a suitable gate decomposition in terms of analog blocks and digital steps. In this way, we show that the quantum dynamics of an enhanced variety of spin models could be implemented with substantially less number of gates than a fully digital approach. Typically, analog blocks are built of multipartite dynamics providing the complexity of the simulated model, while the digital steps are local operations bringing versatility to it. Finally, we describe a possible experimental implementation in trapped-ion technologies.
