论文摘要
我们提出了一个完整的体系结构，用于确定性生成纠缠的多光子状态。我们的方法利用量子点发射极的定期驾驶以及由光子晶体波导启用的有效的光象征界面。我们通过包括所有固有的实验缺陷来评估由实际系统产生的光子状态的质量。重要的是，由于一种自然内置的重新聚在一起方法，该方案对旋转回声的自然内置重聚焦方法是可靠的。我们证明了生产Greenberger-Horne-Zeilinger和一维聚类状态的可行性，其保真度和发电率超过了当前最新实验实验中常规“融合”方法的可行性。提出的硬件构成了一种可扩展和资源有效的方法，用于实施基于测量的量子通信和计算。
We propose a complete architecture for deterministic generation of entangled multiphoton states. Our approach utilizes periodic driving of a quantum-dot emitter and an efficient light-matter interface enabled by a photonic crystal waveguide. We assess the quality of the photonic states produced from a real system by including all intrinsic experimental imperfections. Importantly, the protocol is robust against the nuclear spin bath dynamics due to a naturally built-in refocussing method reminiscent to spin echo. We demonstrate the feasibility of producing Greenberger-Horne-Zeilinger and one-dimensional cluster states with fidelities and generation rates exceeding those achieved with conventional 'fusion' methods in current state-of-the-art experiments. The proposed hardware constitutes a scalable and resource-efficient approach towards implementation of measurement-based quantum communication and computing.
