Jaynes-Cummings-Hubbard阵列为量子仿真提供了独特的机会，因为它们表现出方便的状态制备和测量，以及原位参数调整。我们展示了如何实现强关联态的光在Jaynes-Cummings-Hubbard阵列下的有效磁场的引入。有效场通过腔谐振的动态调谐来实现。通过计算拓扑不变量、拓扑不同态之间的相变和Laughlin波函数重叠，我们证明了Laughlin分数量子霍尔态的存在。
Jaynes-Cummings-Hubbard arrays provide unique opportunities for quantum emulation as they exhibit convenient state preparation and measurement, as well as in situ tuning of parameters. We show how to realize strongly correlated states of light in Jaynes-Cummings-Hubbard arrays under the introduction of an effective magnetic field. The effective field is realized by dynamic tuning of the cavity resonances. We demonstrate the existence of Laughlin-like fractional quantum Hall states by computing topological invariants, phase transitions between topologically distinct states, and Laughlin wave function overlap.
