Non-Abelian Geometric Quantum Gates in Triangular Systems

ArXiv

Analysis

This paper proposes a novel method for creating quantum gates using the geometric phases of vibrational modes in a three-body system. The use of shape space and the derivation of an SU(2) holonomy group for single-qubit control is a significant contribution. The paper also outlines a method for creating entangling gates and provides a concrete physical implementation using Rydberg trimers. The focus on experimental verification through interferometric protocols adds to the paper's value.
Reference

“The paper shows that its restricted holonomy group is SU(2), implying universal single-qubit control by closed loops in shape space.”

Chordality Condition for Holographic Entropy Vectors

Published:Dec 30, 2025 22:19

ArXiv

Analysis

This paper establishes that the 'chordality condition' is both necessary and sufficient for an entropy vector to be realizable by a holographic simple tree graph model. This is significant because it provides a complete characterization for this type of model, which has implications for understanding entanglement and information theory, and potentially the structure of the stabilizer and quantum entropy cones. The constructive proof and the connection to stabilizer states are also noteworthy.
Reference

“The paper proves that the 'chordality condition' is also sufficient.”
