论文摘要
群集状态是实现基于融合的量子计算（FBQC）的基本资源。我们介绍了一种通过利用单一平均概念来生成高保真光学群集状态的方法。这种错误平均技术完全是被动的，可以很容易地将其纳入拟议的Psiquantum的FBQC架构中。使用后选择和融合门的冗余编码，我们观察到输出群集状态的平均保真度的增强。当BSM不完善时，我们还显示了线性光学铃铛测量（BSM）的成功概率的改善。
Cluster states are the essential resource used in the implementation of Fusion-based quantum computation (FBQC). We introduce a method to generate high-fidelity optical cluster states by utilising the concept of unitary averaging. This error averaging technique is entirely passive and can be readily incorporated into the proposed PsiQuantum's FBQC architecture. Using postselection and the redundant encoding of Fusion gates, we observe an enhancement in the average fidelity of the output cluster state. We also show an improvement in the linear optical Bell-state measurement (BSM) success probability when the BSM is imperfect.
