中文摘要：

提出一个改进超导电路结构，此结构能实现量子计算所必需的任意两量子比特之间的长程作用，此结构能用目前技术制作．其次，基于此结构提出Grover搜索算法实现的物理方案．由于能实现任意两量子比特之间的控制相住门，所以多比特Grover搜索算法也能实现，从而满足各种量子计算的需要．此方案是一个基于电流控制的超导电荷比特网络结构的Grover搜索算法实现方案．

英文摘要：

Firstly, we put forward an improved architecture. The improved architecture provides the physical implementations of two-qubit operations between arbitrary pairs of qubits instead of the nearestneighbour qubits. The two-qubit operations between arbitrary pairs of qubits are necessary to the realization of the functional and scalable quantum computer. The proposed architecture is in line with current technology. Secondly, we investigate a scheme for implementing Grover search algorithm via the improved architecture. Since the controlled phase gate between arbitrary pairs of quhits can be realized easily, we can implement multi-qubit Grover search algorithm, which meets the expectations of various quantum computing. It is a simple, scalable and feasible scheme for implementing Grover search algo- rithm based on the current-controlled superconducing charge qubit network.
