论文摘要
量子对话是使用单个通道的两种方式安全和同时通信的过程。最近，已经提出了一项测量设备独立量子对话（MDI-QD）协议（量子信息处理16.12（2017）：305）。为了使协议免受信息泄漏的安全性，作者在误差估计阶段后丢弃了几乎一半的量子位。在本文中，我们提出了两个修改版本的MDI-QD协议，以便在误差估计阶段后将丢弃的量子数减少到几乎四分之一的量子位。我们将几乎一半的丢弃量子与使用的量子位一起使用，以使我们的协议在Qubits计数方面更有效。我们表明，在MDI-QD协议中给出的相同的对抗模型下，我们的两个协议都是安全的。
Quantum dialogue is a process of two way secure and simultaneous communication using a single channel. Recently, a Measurement Device Independent Quantum Dialogue (MDI-QD) protocol has been proposed (Quantum Information Processing 16.12 (2017): 305). To make the protocol secure against information leakage, the authors have discarded almost half of the qubits remaining after the error estimation phase. In this paper, we propose two modified versions of the MDI-QD protocol such that the number of discarded qubits is reduced to almost one-fourth of the remaining qubits after the error estimation phase. We use almost half of their discarded qubits along with their used qubits to make our protocol more efficient in qubits count. We show that both of our protocols are secure under the same adversarial model given in MDI-QD protocol.
