Optimal and Deterministic Quantum Search on the Simplex of Complete Graphs
Kiyoji Huang Fujiwara, Yujia Shi, Thomas G. Wong
The simplex of complete graphs, also known as the first-order truncated simplex lattice, is a network of identical complete graphs, each with vertices, such that each cli…
Resilience by Design: A KPI for Heavy-Duty Megawatt Charging
Sonia Yeh, Rishabh Ghotge, Yujia Shi +1
We introduce a stressor-agnostic Resilience Key Performance Indicator (Resilience KPI) for megawatt charging stations (MSC) serving heavy-duty vehicles. Beyond routine performance…
FreeAnimate: Training-Free Human Image Animation with Preview-Guided Denoising
Yuan Zeng, Yujia Shi, Zongqing Lu +1
Human Image Animation has seen significant advancements, primarily driven by diffusion models. However, existing methods typically demand substantial training data and resources to…
EgoPressDiff: Multimodal Video Diffusion for Egocentric UV-Domain Hand-Pressure Estimation
Yuan Zeng, Zilue Gao, Yujia Shi +3
Estimating hand-surface contact pressure from an egocentric view is crucial for AR/VR devices, robotic imitation, and ergonomic analysis. Existing methods often discretize pressure…
Self-Trapping Bounds for Continuous-Time Nonlinear Quantum Walks on Path and Cycle Graphs
Yujia Shi, Thomas G. Wong
We explore a continuous-time quantum walk starting at a single vertex on the discrete path and cycle with a cubic nonlinearity. Such nonlinearities arise in Bose-Einstein condensat…
Fast state transfer via loop weights
Gabor Lippner, Yujia Shi
We prove that almost-linear-time high-fidelity state transfer is achievable in a quantum spin chain using loop weights at the second and second-to-last nodes. We provide specific p…
