摘要:

量子通信和量子计量是量子信息科学领域备受瞩目的应用,而量子遥感是两者的交叉。尽管存在差异,量子通信和量子遥感之间有着显著的共性,因为它们都通过传输量子态来实现各自的功能。在此,我们提出了一种新颖的量子集成传感与通信(QISAC)协议,它通过传输纠缠,在实现海森堡极限下的量子传感的同时,实现了量子安全通信。我们从理论上证明了其抵御窃听者的安全性。QISAC的安全性通过信息比特的保密容量以及用于传感的非对称Fisher信息增益来表征。通过在有限纠缠资源约束下进行的模拟,我们表明QISAC在相位估计中保持了高精度。因此,我们的QISAC为未来量子网络的应用提供了新视角。

英文摘要:

Quantum communication and quantum metrology are widely compelling applications in the field of quantum information science, and quantum remote sensing is an intersection of both. Despite their differences, there are notable commonalities between quantum communication and quantum remote sensing, as they achieve their functionalities through the transmission of quantum states. Here we propose a novel quantum integrated sensing and communication (QISAC) protocol, which achieves quantum sensing under the Heisenberg limit while simultaneously enabling quantum secure communication through the transmission of entanglements. We have theoretically proven its security against eavesdroppers. The security of QISAC is characterized by the secrecy capacity for information bit as well as asymmetric Fisher information gain for sensing. Through simulations conducted under the constraints of limited entanglement resources, we illustrate that QISAC maintains high accuracy in the estimation of phase. Hence our QISAC offers a fresh perspective for the applications of future quantum networks.
