摘要:

提出了一种基于量子相位估计算法的多轮量子密集编码方案。使用$m+1$量子比特系统,Bob可以通过仅操纵一个量子比特并在Alice和Bob之间交换$m$轮来向Alice发送$2^{m+1}$消息。信息容量被增强到$m+1$比特。我们已经在一个三量子比特的核磁共振(NMR)量子计算机中实现了这个方案.实验结果表明理论与实验结果吻合较好。

英文摘要:

A multiple round quantum dense coding (MRQDC) scheme based on the quantum phase estimation algorithm is proposed. Using an $m+1$ qubit system, Bob can transmit $2^{m+1}$ messages to Alice, through manipulating only one qubit and exchanging it between Alice and Bob for $m$ rounds. The information capacity is enhanced to $m+1$ bits. We have implemented the scheme in a three- qubit nuclear magnetic resonance (NMR) quantum computer. The experimental results show a good agreement between theory and experiment.
