Improving the lower bound to the secret-key capacity of the thermal amplifier channel
Gan Wang, Carlo Ottaviani, Hong Guo +1
We consider the noisy thermal amplifier channel, where signal modes are amplified together with environmental thermal modes. We focus on the secret-key capacity of this channel, wh…

Composable security analysis of continuous-variable measurement-device-independent quantum key distribution with squeezed states for coherent attacks
Ziyang Chen, Yi-Chen Zhang, Gan Wang +2
Measurement-device-independent quantum key distribution protocol, whose security analysis does not rely on any assumption on the detection system, can immune the attacking against…
