abstract

For an algebraic curve $\mathcal{X}$ defined over an algebraically closed field of characteristic $p > 0$, the $a$-number $a(\mathcal{X})$ is the dimension of the space of exact holomorphic differentials on $\mathcal{X}$. We compute the $a$-number for a family of certain Picard curves, using the action of the Cartier operator on $H^0(\mathcal{X},\Omega^1)$.

  1. Reinforcement Learning Enhanced Greedy Decoding for Quantum Stabilizer Codes over $\mathbb{F}_q$

    quant-ph 2025-06 reject novelty 3.0 of 10

    A claimed [[27,13,4]]_3 qutrit code from separated-polynomial curves and an RL-on-Greedy decoder are presented, but internal math inconsistencies and missing simulation data undermine the claims.
