摘要:

输运现象仍然是计算物理中最具挑战性的问题之一。通过利用狄拉克和格子玻尔兹曼方程之间的类比,我们开发了一个基于赝自旋玻色子量子系统的量子模拟器,它适用于编码流体动力学输运现象的晶格动力学形式主义。它表明,流和碰撞过程的格子玻尔兹曼动力学可以实现与控制量子操作,使用一个预示的量子协议编码非幺正散射过程。所提出的模拟器适合于在受控量子平台上实现,例如离子阱量子计算机或电路量子电动力学处理器。

英文摘要:

Transport phenomena still stand as one of the most challenging problems in computational physics. By exploiting the analogies between Dirac and lattice Boltzmann equations, we develop a quantum simulator based on pseudospin-boson quantum systems, which is suitable for encoding fluid dynamics transport phenomena within a lattice kinetic formalism. It is shown that both the streaming and collision processes of lattice Boltzmann dynamics can be implemented with controlled quantum operations, using a heralded quantum protocol to encode non-unitary scattering processes. The proposed simulator is amenable to realization in controlled quantum platforms, such as ion-trap quantum computers or circuit quantum electrodynamics processors.
