The system achieved a transmission speed of 214Gbps over 50km of SSMF, showing efficient performance.
Masking information bits effectively prevents low-order demodulation attacks, with minimal impact on performance.
The demonstrated optical power penalty was only 0.5dB, indicating robust communication quality.
Use of quantum phase diffusion enhances the security of the cipher system against current threats.

Implication

Experimental transmission of a 214Gbps Y-00 cipher over 50km SSMF demonstrates resilience against demodulation attack, indicating enhanced security.

Abstract

We experimentally demonstrate a 214Gbps Y-00 cipher transmission based on quantum phase diffusion over 50km SSMF. The masking of information bits can resist the latest low-order demodulation attack, with only a 0.5dB optical power penalty.
