论文摘要
追求以拓扑顺序实现物质的新阶段是一项重要的追求，对密切相关的物理和量子信息的影响。利用对人工量子系统（例如超导电路）的最先进的相干控制的想法，我们提出了一项建议，通过使用交错的磁通图案创建几乎平坦的拓扑带，以在小晶格上实现玻色粒分数量子厅物理。可以通过几乎完美的量化使用24个晶格位点（两个光子）观察到通过电荷泵进行分数化的指纹。我们建议使用具有三角形和方格的圆柱连通性的超导量子位的有限晶格实现。
The quest to realize novel phases of matter with topological order is an important pursuit with implications for strongly correlated physics and quantum information. Utilizing ideas from state-of-the-art coherent control of artificial quantum systems such as superconducting circuits, we present a proposal to realize bosonic fractional quantum Hall physics on small lattices by creating nearly flat topological bands using staggered flux patterns. Fingerprints of fractionalization through charge pumping can be observed with nearly perfect quantization using as few as 24 lattice sites (two photons). We suggest an implementation using a finite lattice of superconducting qubits with cylindrical connectivity on both triangular and square lattices.
