论文摘要
由于线性光学两光子门具有固有的概率，因此基于测量的实现特别适合光子平台：一种称为图形状态的大型高度输入的光子资源状态，是通过测量来执行计算的。因此，挑战是产生这些图形状态。已经提出了使用相互作用的量子发射器或有效的自旋光子界面的几种生成过程，以确定性地创建这些光子图状态。但是，由于最新的线性图状态的产生，这些解决方案仍然无法实验。在这里，我们使用当前的量子发射极功能介绍了近确定的解决方案，以生成图形状态。我们提出了基于量子发射体的杂交量图生成与全球融合门的生成，以近确定性地产生复杂拓扑的图形状态。我们的结果应为实践的实际实施铺平了资源有效的量子信息处理，包括基于测量的量子通信和量子计算。
Since linear-optical two-photon gates are inherently probabilistic, measurement-based implementations are particularly well suited for photonic platforms: a large highly-entangled photonic resource state, called a graph state, is consumed through measurements to perform a computation. The challenge is thus to produce these graph states. Several generation procedures, which use either interacting quantum emitters or efficient spin-photon interface, have been proposed to create these photonic graph states deterministically. Yet, these solutions are still out of reach experimentally since the state-of-the-art is the generation of a linear graph state. Here, we introduce near-deterministic solutions for the generation of graph states using the current quantum emitter capabilities. We propose hybridizing quantum-emitter-based graph state generation with all-photonic fusion gates to produce graph states of complex topology near-deterministically. Our results should pave the way towards the practical implementation of resource-efficient quantum information processing, including measurement-based quantum communication and quantum computing.
