论文摘要
具有树型纠缠结构的光子簇状态构成了光子损失量子误差校正的有效资源。但是，众所周知，具有任意大小的树簇状态的产生很困难。在这里，我们提出了一种协议，以确定性地生成任意大小的光子树状态，仅使用单个量子发射极。光子纠缠是通过从同一发射极的发射和重新散落的，从而能够快速和资源的纠缠产生。也可以扩展相同的协议以生成更通用的树型纠缠状态。
A photonic cluster state with a tree-type entanglement structure constitutes an efficient resource for quantum error correction of photon loss. But the generation of a tree cluster state with an arbitrary size is notoriously difficult. Here, we propose a protocol to deterministically generate photonic tree states of arbitrary size by using only a single quantum emitter. Photonic entanglement is established through both emission and re-scattering from the same emitter, enabling fast and resource-efficient entanglement generation. The same protocol can also be extended to generate more general tree-type entangled states.
