What happened
This is an arXiv feed (2026-03-11) aggregating multiple research papers across information theory, coding, privacy, and wireless communications. Key contributions include: (1) capacity result showing feedback does not increase capacity for a class of approximately memoryless surjective POST channels; (2) proof of equivalence between linear perfect zero-knowledge codes and quantum CSS codes, enabling explicit asymptotically-good zero-knowledge locally-testable codes; (3) generalization of differentially private secure multiplication to M multiplicands with encoding-polynomial and layered-noise/
