研究了玻色子两体量子行走中相互作用对量子关联传播的影响。相互作用和Hanbury Brown\char21{}Twiss干扰的组合效应导致独特的空间相关性，其取决于相互作用的强度，但不取决于其符号。我们利用在高度非线性光子晶格中传播的光，实验测量了这些效应的弱相互作用极限。最后，我们提出了一种在光晶格中利用少量原子观察强相互作用极限的实验方法。
We study the effect of interactions on the propagation of quantum correlations in the bosonic two-body quantum walk. The combined effect of interactions and Hanbury Brown\char21{}Twiss interference results in unique spatial correlations which depend on the strength of the interaction, but not on its sign. We experimentally measure the weak interaction limit of these effects using light propagating in a highly nonlinear photonic lattices. Finally, we propose an experimental approach to observe the strong interaction limit using few atoms in optical lattices.
