我们提出了多方纠缠净化协议，能够直接净化任意图形状态。我们开发的复发和繁殖协议，并比较我们的方法与策略的基础上，在静态和通信的情况下，二分纠缠纯化。我们发现，直接多方净化是有利的可实现的产量和最小所需的保真度在静态的情况下，在这两种情况下的嘈杂的操作的情况下，可获得的保真度。
We present multiparty entanglement purification protocols that are capable of purifying arbitrary graph states directly. We develop recurrence and breeding protocols and compare our methods with strategies based on bipartite entanglement purification in static and communication scenarios. We find that direct multiparty purification is of advantage with respect to achievable yields and minimal required fidelity in static scenarios, and with respect to obtainable fidelity in the case of noisy operations in both scenarios.
