Generation of entangled state is of paramount importance both from quantum theoretical foundation and technology applications. Entanglement swapping provides an efficient method to generate entanglement in quantum communication protocols. However, perfect Bell measurements for qudits, the key to entanglement swapping, have been proven impossible to achieve by using only linear elements and particle detectors. To avoid this bottleneck, we propose a scheme to generate entangled state including two-qubit entangled state, two-qudit entangled state, three-qubit GHZ state and three-qudit GHZ state between several designate parties via the model of quantum walks with multiple coins. Then we conduct experimental realization of Bell state and three-qubit GHZ state between several designate parties on IBM quantum platform and the result has high fidelity by performing quantum tomography. In the end, we give a practical application of our scheme in multiparty quantum secret sharing.

纠缠态的产生对于量子理论基础和技术应用都至关重要。纠缠交换提供了一种在量子通信协议中产生纠缠的有效方法。但是，事实证明，仅使用线性元素和粒子检测器就无法实现对纠缠交换的关键的Qudits的完美Bell测量。为了避免这种瓶颈，我们提出了一种通过多个硬币的量子行走模型在多个指定方之间生成包括两个量子纠缠态，两个量子纠缠态，三个量子纠缠态和三个量子纠缠态的纠缠态的方案。 。然后，我们在IBM量子平台上的几个指定方之间进行了贝尔状态和三量子比特GHZ状态的实验实现，并且通过执行量子层析成像，结果具有很高的保真度。最后，给出了该方案在多方量子秘密共享中的实际应用。
