The field of coding theory is witnessing significant advancements, particularly in the areas of quantum error correction and self-dual codes. Quantum Locally Recoverable Codes (qLRCs) are gaining traction due to their potential in quantum data storage systems, with new constructions and improved minimum distance bounds being developed. Self-dual cyclic codes are also making strides, with novel approaches leading to infinite families of codes that exhibit square-root-like lower bounds on their minimum distances, a breakthrough in Euclidean self-dual binary cyclic codes. Additionally, the study of codes with restricted overlaps is expanding, offering new constructions and bounds that enhance the efficiency and reliability of data transmission. Notably, the introduction of unbounded error-correcting codes presents a novel approach to error correction without a predetermined length, offering nearly-tight bounds on code rates and distances, which could revolutionize the field in the context of adversarial and random noise scenarios.

Noteworthy papers include one on quantum LRCs that introduces a flexible construction method using good polynomials, and another on self-dual cyclic codes that constructs an infinite family with a square-root-like lower bound, significantly advancing the understanding of these codes.
