论文摘要
图表是解决自然科学跨科学复杂问题的强大概念，因为连通性的模式会导致多种新兴现象。基于图的方法已被证明在高度分支的量子网络中的量子通信和量子搜索算法中特别富有成果。在这里，我们引入了一种新的范式，用于通过利用与量身定制的双重双向的复杂波导电路中的空间和极化自由度的混合作用来直接实现与三维网络相关的激发动力学。在复杂的高度连接图上，对多粒子量子行走进行实验探索的新型测试床为利用综合量子光子学中费米尼克动力学的应用潜力铺平了道路。
Graph representations are a powerful concept for solving complex problems across natural science, as patterns of connectivity can give rise to a multitude of emergent phenomena. Graph-based approaches have proven particularly fruitful in quantum communication and quantum search algorithms in highly branched quantum networks. Here we introduce a new paradigm for the direct experimental realization of excitation dynamics associated with three-dimensional networks by exploiting the hybrid action of spatial and polarization degrees of freedom of photon pairs in complex waveguide circuits with tailored birefringence. This novel testbed for the experimental exploration of multi-particle quantum walks on complex, highly connected graphs paves the way towards exploiting the applicative potential of fermionic dynamics in integrated quantum photonics.
