Quantum key distribution (QKD) is the best candidate for securing communications against attackers, who may in the future exploit quantum-enhanced computational powers to break classical encryption. As such, new challenges are arising from our need for large-scale deployment of QKD systems. In a realistic scenario, transmitting and receiving devices from different vendors should be able to communicate with each other without the need for matching hardware. Therefore, practical deployment of QKD would require hardware capable of adapting to different protocols and clock rates. Here, we address this challenge by presenting a multi-rate, multi-protocol QKD transmitter linked to a correspondingly adaptable QKD receiver. The flexibility of the transmitter, achieved by optical injection locking, allows us to connect it with two receivers with inherently different clock rates. Furthermore, we demonstrate the multi-protocol operation of our transmitter, communicating with receiving parties employing different decoding circuits.

多速率、多协议量子密钥分发发射机的实时运行
量子密钥分发 (QKD) 是保护针对攻击者的通信的最佳候选者,攻击者将来可能会利用量子增强的计算能力来破解经典加密。因此,我们需要大规模部署 QKD 系统,这带来了新的挑战。在现实场景中,来自不同供应商的发送和接收设备应该能够相互通信,而无需匹配硬件。因此,QKD 的实际部署需要能够适应不同协议和时钟速率的硬件。在这里,我们通过提供链接到相应适应性 QKD 接收器的多速率、多协议 QKD 发送器来解决这一挑战。通过光学注入锁定实现的发射器的灵活性,允许我们将其与两个具有固有不同时钟速率的接收器连接。此外,我们演示了我们的发射机的多协议操作,与使用不同解码电路的接收方进行通信。
