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…

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…
