Distributed synthesis of arbitrary graph states in quantum networks via rank-two GF(2) reduction

Xiaoyi Zheng, Lin Chen, Chan-Tong Lam

Existing schemes for synthesizing graph states in quantum networks are essentially edge-by-edge constructions, so quantities such as the time-slot depth and the resource overhead g…

Geometric Collapse: When Vision Models Fail to Verify Physical Causality

Wentao Zhang, Jinhu Qi, Weiqiang Jin +3

Recent progress in large-scale self-supervised learning has improved dense geometric prediction, but it remains unclear whether such scaling yields inference-time physical plausibi…

Scalable Graph State Generation with O(1) Local Feedforward in Quantum Networks

Xiaoyi Zheng, Chan-Tong Lam, Lin Chen +1

The development of quantum networks faces a key challenge: the contradiction between probabilistic long-range entanglement generation and finite coherence time. Existing routing pr…

Generating 2-Gray codes for grand Motzkin paths and grand Dyck paths with air pockets in constant amortized time

Lei Dong, Bowie Liu, Dennis Wong +3

A grand Motzkin path with air pockets is a non-empty lattice path in the first and fourth quadrant of , starting at the origin , ending on the -axis, and co…

A Unified Non-Parametric and Interpretable Point Cloud Analysis via t-FCW Graph Representation

Haijian Lai, Bowen Liu, Man Xu +4

We introduce an empowered transposed Fully Connected Weighted (t-FCW) graph representation to embed point clouds into a metric space. While original t-FCW has shown promising resul…

Generating pivot Gray codes for spanning trees of complete graphs in constant amortized time

Bowie Liu, Dennis Wong, Chan-Tong Lam +1

We present the first known pivot Gray code for spanning trees of complete graphs, listing all spanning trees such that consecutive trees differ by pivoting a single edge around a v…
