帕多瓦经典网络基础设施上的部署就绪量子密钥分发
Deployment-ready quantum key distribution over a classical network infrastructure in Padua
摘要：
当前的技术进步正在推动量子密钥分发向商业和世界规模的扩展。它提供无条件安全通信的能力将是下一代电信网络的基本特征。然而，在实际操作场景中实现QKD以及与经典电信基础设施共存的演示对于可靠的开发至关重要。在这里，我们提出了一个量子密钥分发应用程序实现了一个经典的基于光纤的基础设施。通过利用一个单一的光纤电缆的量子和经典的信道，并通过使用一个简化的接收机方案，只有一个单光子探测器，我们证明了低成本和现成的量子密钥分发系统与标准的经典基础设施兼容的可行性。
英文摘要：
Current technological progress is driving Quantum Key Distribution towards a commercial and world widescale expansion. Its capability to deliver unconditionally secure communication will be a fundamental feature in the next generations of telecommunication networks. Nevertheless, demonstrations of QKD implementation in a real operating scenario and their coexistence with the classical telecom infrastructure are of fundamental importance for reliable exploitation. Here we present a Quantum Key Distribution application implemented overa classical fiber-based infrastructure. By exploiting just a single fiber cable for both the quantum and the classical channel and by using a simplified receiver scheme with just one single-photon detector, we demonstrate the feasibility of low-cost and ready-to-use Quantum Key Distribution systems compatible with standard classical infrastructure.
