我们开发了一个方案，用于产生一个通用的量子比特团簇状态使用概率贝尔测量，而不需要前馈。借用的想法，从渗流理论，我们数值计算表明，使用明确的贝尔测量，成功与75%的成功概率，可以建立一个集群状态的基础烧绿石几何形状，这样的概率有一个跨越集群接近统一的无限晶格尺寸的限制。在我们的协议中，生成普适状态所需的初始资源是实验范围内的三个量子位簇状态，并且是基于Bell测量的渗透提案的最小资源。由于单光子和多光子损失可以检测到贝尔测量，我们的协议提出了一个完全错误鲁棒性计划的前景。
We develop a scheme for generating a universal qubit cluster state using probabilistic Bell measurements without the need for feed-forward. Borrowing ideas from percolation theory, we numerically show that using unambiguous Bell measurements that succeed with 75% success probability one could build a cluster state with an underlying pyrochlore geometry such that the probability of having a spanning cluster approaches unity in the limit of infinite lattice size. The initial resources required for the generation of a universal state in our protocol are three-qubit cluster states that are within experimental reach and are a minimal resource for a Bell-measurement-based percolation proposal. Since single and multiphoton losses can be detected in Bell measurements, our protocol raises the prospect of a fully error-robust scheme.
