【摘要】：应用量子隐形传态将Broadbent等人提出的通用盲量子计算(universal blind quantum computation)模型和辅助量子比特驱动型量子计算(ancilla-driven universal quantum computation)模型进行结合,构造一个新的混合模型来进行计算。此外,用计算寄存器对量子纠缠的操作来代替量子比特测量操作。因为后者仅限于两个量子比特,所以代替后的计算优势十分明显。基于上述改进,设计了实现辅助驱动型通用盲量子计算的协议。协议的实现,能够使Anders等人的辅助驱动型量子计算增强计算能力,并保证量子计算的正确性,从而使得参与计算的任何一方都不能获得另一方的保密信息。
[Abstract]:By means of quantum teleportation, the general blind quantum computation (universal blind quantum computation) model proposed by Broadbent et al is combined with the auxiliary quantum bit driven quantum computation (ancilla-driven universal quantum computation) model to construct a new hybrid model for computation. In addition, the quantum bit measurement operation is replaced by the quantum entanglement operation of the computational register. Since the latter is limited to only two qubits, the computational advantage of the replacement is obvious. Based on the above-mentioned improvements, a protocol for the implementation of auxiliary-driven universal blind quantum computing is designed. The implementation of the protocol can enhance the computing ability of Anders et al's auxiliary-driven quantum computing and guarantee the correctness of quantum computing so that neither party involved in the computation can obtain the confidential information of the other side.
