Nonplanar qubit with tunable gauge symmetry
Muqing Yu, Han Bi, Hengli Lo +6
The authors build a non‑planar superconducting qubit using a 3×3 crossbar Josephson array that exhibits a flux‑tunable \(\mathbb{Z}_3\) combinatorial gauge symmetry, and demonstrat…
Inter-band optical transitions of helical Majorana edge modes in topological superconductors
Han Bi, James Jun He
The search for evidence of Majorana states on the edges of topological superconductors (TSCs) is challenging due to the difficulty of detecting such charge-neutral electronic quasi…
Better NTK Conditioning: A Free Lunch from (ReLU) Nonlinear Activation in Wide Neural Networks
Chaoyue Liu, Han Bi, Like Hui +1
Nonlinear activation functions are widely recognized for enhancing the expressivity of neural networks, which is the primary reason for their widespread implementation. In this wor…
VM-BHINet:Vision Mamba Bimanual Hand Interaction Network for 3D Interacting Hand Mesh Recovery From a Single RGB Image
Han Bi, Ge Yu, Yu He +2
Understanding bimanual hand interactions is essential for realistic 3D pose and shape reconstruction. However, existing methods struggle with occlusions, ambiguous appearances, and…
Optical response of edge modes in time-reversal symmetric topological superconductors
Hirokazu Kobayashi, Han Bi, James Jun He +1
Topological superconductors and Majorana edge modes at their boundaries have been theoretically predicted. However, their experimental observation remains controversial. Recent the…
