辅助量子比特驱动型通用盲量子计算

Ancilla-driven universal blind quantum computation

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。

This paper proposed a protocol for aneilla-driven universal blind quantum computation by incorporating the idea of quantum teleportation model to computation named as ＂universal blind quantum computation＂ by Broadbent et al. In addition, it used compute register＇ s operate on quantum entanglement to replace the measurement of the quantum bit. Because the latter was limited to two qubits＇ measurement, the former had an obvious advantage. Based on these improvements it designed a pro- tocol to achieve ancilla-driven universal blind quantum computation. This protocol could regarded as a blind version of ＂ancil- la-driven universal quantum computation＂ due to Anders et al, improve its computing ability, and ensure the compute correct- ness, so that any party involved in this computation cannot get the other party＇ s privacy information.
