On the Photon Subtraction-Based Measurement-Device-Independent CV-QKD Protocols
IEEE Access, 2019 To potentially overcome the practical security loopholes of CV-QKD protocols, in this paper, we propose to use the optimized eight-state measurement-device-independent (MDI) protocol and demonstrate that it can significantly outperform corresponding ...

Spectral characterisation of the dicode PPM format [PDF]
, 2005 Dicode pulse position modulation (PPM) is a new modulation format that offers improved sensitivity over digital PPM but at a reduced line-rate. This Letter considers, for the first time, the spectral characterisation of the dicode PPM modulation format ...

Support Size of ε-Capacity-Achieving Inputs for the Amplitude-Constrained AWGN Channel
EntropyWe study the discrete-time amplitude-constrained additive white Gaussian noise (AWGN) channel from the perspective of near-optimal input distributions in the high-SNR, or equivalently large-amplitude, regime. While it is known that the capacity-achieving

Asymptotic Security Analysis of Discrete-Modulated Continuous-Variable Quantum Key Distribution
Physical Review X, 2019 Continuous-variable quantum key distribution (CV QKD) protocols with discrete modulation are interesting due to their experimental simplicity and their great potential for massive deployment in the quantum-secured networks, but their security analysis is
