Symmetry-protected privacy: beating the rate-distance linear bound over a noisy channel
Pei Zeng, Weijie Wu, Xiongfeng Ma
There are two main factors limiting the performance of quantum key distribution --- channel transmission loss and noise. Previously, a linear bound was believed to put an upper lim…

Surpassing the rate-transmittance linear bound of quantum key distribution
Xiao-Tian Fang, Pei Zeng, Hui Liu +17
Quantum key distribution (QKD offers a long-term solution to establish information-theoretically secure keys between two distant users. In practice, with a careful characterization…
