摘要:

纠缠多光子态的片上稳健产生和操纵在量子计算和通信中具有重要作用。晶格拓扑已经成为一种保护光子态不受无序影响的手段,但不同拓扑之间的纠缠尚未被探索。我们报道了在硅波导的二分阵列中拓扑不同的空间模式之间的双光子纠缠。结果突出拓扑作为一个额外的自由度纠缠和开放的途径,调查平凡和拓扑模式之间的信息隐形传态。

英文摘要:

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.
