Beyond Repetition: Sharper Bounds for Quantum Channel Capacity
New research demonstrates how stabilizer codes and induced channel analysis can refine our understanding of how much information can be reliably transmitted through noisy quantum channels.


![The study demonstrates that spin singlets, arranged around a vortex core carrying a spin of [latex]\frac{1}{2}[/latex], locally restore four-fold lattice rotation symmetry, indicating a fundamental relationship between spin configuration and symmetry in the system.](https://arxiv.org/html/2601.14398v1/x1.png)


![The study of pentaquark decay pathways-specifically [latex]Pc(4410) \rightarrow \eta_c \Delta[/latex] and [latex]Pc(4410) \rightarrow J/\psi \Delta[/latex]-reveals sensitivity to Borel window variations, suggesting a nuanced relationship between decay constants and the parameters used in analyzing hadron interactions.](https://arxiv.org/html/2601.14723v1/x4.png)
