论文摘要
量子模拟是量子技术的支柱之一。这些模拟提供了像高能量物理，多体物理学或宇宙学一样多样化的洞察力，仅举几例。已经提出，已经提出了几个平台，从超电原子到通过被困离子的超导电路作为量子模拟器。本文回顾了另一个建立良好的量子模拟平台中的最新发展：半导体微腔中的极化子。这些准颗粒遵守非线性schrödigner方程（NLSE），可以从量子流体动力学方面理解它们在培养基中的传播。因此，它们被认为是“光的流体”。量子模拟的挑战是配置的工程，其中可以控制NLSE中的势能和非线性相互作用。在这里，我们在微腔中重新访问了一些具有偏振子的具有里程碑意义的实验，讨论如何在量子模拟中使用这些系统的各种特性，并突出显示了极化系统的丰富性来探索非平衡物理学
Quantum simulations are one of the pillars of quantum technologies. These simulations provide insight in fields as varied as high energy physics, many-body physics, or cosmology to name only a few. Several platforms, ranging from ultracold-atoms to superconducting circuits through trapped ions have been proposed as quantum simulators. This article reviews recent developments in another well established platform for quantum simulations: polaritons in semiconductor microcavities. These quasiparticles obey a nonlinear Schrödigner equation (NLSE), and their propagation in the medium can be understood in terms of quantum hydrodynamics. As such, they are considered as "fluids of light". The challenge of quantum simulations is the engineering of configurations in which the potential energy and the nonlinear interactions in the NLSE can be controlled. Here, we revisit some landmark experiments with polaritons in microcavities, discuss how the various properties of these systems may be used in quantum simulations, and highlight the richness of polariton systems to explore non-equilibrium physics
