论文摘要
相干的光子发射极接口提供了一种介导有效的非线性光子光子相互作用的方法，这对于量子信息处理急需。在这里，我们通过实验研究了两级发射极的情况，即量子点，并在纳米光指导中耦合到单个光学模式。我们进行了很少的光子传输实验，并记录了光的统计数据，以重建1和2光子组件的散射矩阵元件。这为复杂的非线性光子相互作用提供了直接的见解，该相互作用包含丰富的多体物理学。
Coherent photon-emitter interfaces offer a way to mediate efficient nonlinear photon-photon interactions, much needed for quantum information processing. Here we experimentally study the case of a two-level emitter, a quantum dot, coupled to a single optical mode in a nanophotonic waveguide. We carry out few-photon transport experiments and record the statistics of the light to reconstruct the scattering matrix elements of 1- and 2-photon components. This provides direct insight to the complex nonlinear photon interaction that contains rich many-body physics.
