中文摘要：

高度纠缠的簇态是一种常见的测量基的量子计算的资源。提出了基于约瑟夫森比特的簇态实现方案。方案简单且易于操作，每个量子比特是通过包括一个超导岛和一个库伯对盒来实现的，任意两个约瑟夫森结量子比特可以通过一个对称的直流射频超导干涉仪相互耦合。通过调节每个实现量子比特的门电压，来设定合适的初态，通过调节系统内相应的参量从而实现一个一个环路的耦合作用，以实现簇态。经过理论推导，方案简便易操作。在现在的技术条件下，方案完全可行。

英文摘要：

Highly entangled states called cluster states are an universal resource for measurement based quantum computing （QC）. Based on the Josephson charge qubits, a scheme for generating cluster states is proposed. The scheme is simple and easily manipulated, because any two charge qubits based on Josephson junction can be selectively and effectively coupled by a symmetric dc superconducting quantum interference device （SQUID）. Initially state can be generated via changing the gate voltages, and couple charge qubits by choosing the suitable parameters. All the devices in the scheme are within the current technology.
