论文摘要
在此贡献中，我们考虑了一个有利的构建块，具有各种量子应用的潜力：基于耦合旋转的设备，能够生成和共享一对Qubits对。我们的模型设备是一个二聚旋转链，具有三个弱耦合嵌入的位点（缺陷）。在[1]和[2]中提出了三种不同的纠缠方案，其中一个产生簇状态，两种产生铃铛状态，具体取决于初始状态注入。在这里，我们比较了此类方案的鲁棒性，例如与不同类型的制造（静态能量波动）和操作（时机注入延迟）误差等量子纠缠的门。
In this contribution we consider an advantageous building block with potential for various quantum applications: a device based on coupled spins capable of generating and sharing out an entangled pair of qubits. Our model device is a dimerised spin chain with three weakly coupled embedded sites (defects). Three different entangling protocols were proposed for this chain in [1] and [2], one producing a Cluster state and two generating a Bell state, depending on the initial state injection. Here we compare the robustness of such protocols as quantum entangling gates against different types of fabrication (static energy fluctuations) and operation (timing injection delays) errors.
