摘要:

我们提出一种基于级联量子阱结构阶梯自发辐射的纠缠多光子态确定性源。量子阱之间的耦合使得多路径演化能够发射三模光子数组合态。该三方多光子态可通过测量第三模来控制两个多光子模之间的纠缠。我们进一步讨论了其作为带有错误检测辅助比特的量子比特对源的应用。

英文摘要:

We propose a deterministic source of entangled multiphoton states based on spontaneous emission from a ladder of a cascaded quantum well structure. The coupling between the quantum wells enables a many-path evolution with the emission of photon-number combination states in three modes. The tripartite multiphoton state can be used for controlling the entanglement between two multiphoton modes by measuring the third. We further discuss an application as a qubit-pair source with an error-detection ancilla.
