Strengthening practical continuous-variable quantum key distribution systems against measurement angular error
Tao Shen, Yundi Huang, Xiangyu Wang +3
The optical phase shifter that constantly rotates the local oscillator phase is a necessity in continuous-variable quantum key distribution systems with heterodyne detection. In pr…
Practical continuous-variable quantum key distribution using dynamic digital signal processing: security proof and experimental demonstration
Lu Fan, Zhengyu Li, Sheng Liu +8
Digital signal processing technology has paved the way for the realization of high-speed continuous-variable quantum key distribution systems. However, existing security proofs are…
Open/closed Correspondence via Relative/local Correspondence
Chiu-Chu Melissa Liu, Song Yu
We establish a correspondence between the disk invariants of a smooth toric Calabi-Yau 3-fold with boundary condition specified by a framed Aganagic-Vafa outer brane a…
Improvement of two-way continuous-variable quantum key distribution using optical amplifiers
Yi-Chen Zhang, Zhengyu Li, Christian Weedbrook +5
The imperfections of a receiver's detector affect the performance of two-way continuous-variable quantum key distribution protocols and are difficult to adjust in practical situati…
Continuous-mode analysis for practical continuous-variable quantum key distribution
Yanhao Sun, Jiayu Ma, Xiangyu Wang +3
Continuous-variable quantum key distribution (CV-QKD) enables two remote parties to establish information-theoretically secure keys and offers high practical feasibility due to its…
Symmetries of Spatial Graphs in -manifolds
Erica Flapan, Song Yu
We consider when automorphisms of a graph can be induced by homeomorphisms of embeddings of the graph in a -manifold. In particular, we prove that every automorphism of a graph…
