Semiquantum private comparison via cavity QED
AI总结：
提出首个基于腔 QED 与原子演化规律的 SQPC 协议，使两个能力受限的半量子方在半诚实 TP 协助下比较私有输入是否相等，且无需酉操作、纠缠交换或延迟线，并可抵御内外部攻击。
摘要：
本文设计了首个利用原子演化规律、通过腔量子电动力学（QED）实现的半量子隐私比较（SQPC）协议。在半诚实第三方（TP）的协助下，该协议能够比较两个仅具备有限量子能力的半量子参与方的私有输入是否相等。所提协议采用直积态作为初始量子资源，并且不使用任何酉操作、量子纠缠交换操作或延迟线。安全性证明表明，该协议能够同时抵御外部攻击和内部攻击。
英文摘要：
In this paper, we design the first semiquantum private comparison (SQPC) protocol which is realized via cavity quantum electrodynamics (QED) by making use of the evolution law of atom. With the help of a semi-honest third party (TP), the proposed protocol can compare the equality of private inputs from two semiquantum parties who only have limited quantum capabilities. The proposed protocol uses product states as initial quantum resource and employs none of unitary operations, quantum entanglement swapping operation or delay lines. Security proof turns out that it can defeat both the external attack and the internal attack.
