论文摘要
芯片上纠缠多光子状态的强大生成和操纵在量子计算和通信中具有至关重要的作用。晶格拓扑已成为保护光子状态免受疾病的一种手段，但跨不同拓扑的纠缠仍未开发。我们报告了硅波导两分阵列中拓扑不同的空间模式之间的两光子纠缠。结果凸显了拓扑是纠缠纠缠和开放途径的额外自由度，以调查微不足道和拓扑模式之间的信息传送。
The robust generation and manipulation of entangled multiphoton states on-chip has an essential role in quantum computation and communication. Lattice topology has emerged as a means of protecting photonic states from disorder but entanglement across different topologies remained unexplored. We report biphoton entanglement between topologically distinct spatial modes in a bipartite array of silicon waveguides. The results highlight topology as an additional degree of freedom for entanglement and open avenues for investigating information teleportation between trivial and topological modes.
