The Capacity of a Family of Sticky Channels
Mladen KovaÄeviÄ
The paper exactly determines the Shannon and zero‑error capacity of a family of q‑ary sticky‑insertion (repeat) channels, showing it equals log₂ λ bits per symbol under specific re…

Superadditivity for Entanglement-Assisted Communication
Hao-Chung Cheng, Mario Berta
The paper demonstrates that, although the entanglement‑assisted capacity of a quantum channel is additive, the reliability (error exponent) can be strictly superadditive, meaning j…

Capacity of Uniform Noise Channels Under Average Input Power Constraints
Yihan Zhang
The paper determines the exact capacity of additive channels with uniformly distributed noise under an average input power constraint, and identifies the optimal input and output d…
