论文摘要
我们提出了一种仅使用给定状态的稳定器发电机来计算完全在稳定器形式中的图形状态的纯度。我们应用这种方法来找到图形状态的浓缩纠缠，其中包括任何图状态中的单个量子，提议在量子中rep绕和最大化整体浓缩纠缠的量子和状态。
We propose a method to calculate the purity of reduced states of graph states entirely within the stabilizer formalism, using only the stabilizer generators for a given state. We apply this method to find the Concentratable Entanglement of graph states, with examples including a single qubit within any graph state, states proposed for use in quantum repeaters and states that maximise and minimise the overall Concentratable Entanglement.
