论文摘要
在解决某些任务方面，超牢固的状态可以胜过其经典的同行。在这里，我们提出了一个简化的方案，以完全区分两光子的超置钟状态，以极化，空间和时态自由度（DOFS）。单位点（QD）之间可以原则上实现统一的忠诚度，而单光子检测器可以预防不完整和不完美的QD-cavity相互作用。另外，我们的计划中不需要辅助光子或DOF。必要的线性光学元素少于基于奇偶校验检查的光学元素。
Hyperentangled states can outperform their classical counterparts on solving certain tasks. Here we present a simplified scheme for completely distinguishing two-photon hyperentangled Bell states in polarization, spatial, and time-bin degrees of freedom (DOFs). Unity fidelity can be achieved in principle without strong couple limitation between photon and quantum dot (QD), and the incomplete and imperfect QD-cavity interactions are prevented by single-photon detectors. In addition, auxiliary photons or DOFs are not required in our scheme. The necessary linear optical elements are fewer than the parity-check-based one.
