论文摘要
到目前为止,关键分布过程中的无条件安全性仅限于基于非正交碱基定理的量子密钥分布(QKD)协议。最近,已提出了一种完全不同的方法,即无条件安全的经典钥匙分布(USCKD),以实现纯粹的古典制度中的无条件安全性。与QKD不同,经典的通道和正交碱基都是USCKD中的关键成分,在该成分中,通过基于路径叠加的基于路径叠加的可逆统一转换,在耦合的Mach-Zehnder干涉仪中提供了无条件的安全性。在这里,提出了USCKD协议的第一个实验演示。
So far, unconditional security in key distribution processes has been confined to quantum key distribution (QKD) protocols based on the no-cloning theorem of nonorthogonal bases. Recently, a completely different approach, the unconditionally secured classical key distribution (USCKD), has been proposed for unconditional security in the purely classical regime. Unlike QKD, both classical channels and orthogonal bases are key ingredients in USCKD, where unconditional security is provided by deterministic randomness via path superposition-based reversible unitary transformations in a coupled Mach-Zehnder interferometer. Here, the first experimental demonstration of the USCKD protocol is presented.
