渐近安全的量子不经意传输

Asymptotically Secure Quantum Oblivious Transfer

K. Y. Cheong, Min-Hsiu Hsieh, Takeshi Koshiba

摘要:

由于众所周知的不可能性结果,即使在量子世界中,不经意传输的无条件安全性也被认为是不可能的。在本文中,我们试图克服这些不可能的结果,提出了一个协议是渐近安全的。该协议利用了非正交量子态的基本性质。除了安全性之外,我们协议的优点还包括诚实的参与者不需要拥有量子存储器或在单个量子位之间产生纠缠。我们的工作的关系,已知的不可能的结果进行了讨论。

英文摘要:

Due to the commonly known impossibility results, unconditional security for oblivious transfer is seen as impossible even in the quantum world. In this paper, we try to overcome these impossibility results by proposing a protocol which is asymptotically secure. The protocol makes use of the basic properties of non-orthogonal quantum states. Apart from security, the advantages of our protocol include the fact that the honest players do not need to have quantum memory or create entanglement between individual qubits. The relation of our work to the known impossibility results is also discussed.
