  • Tensor-Network Decoding Beyond 2D

    Author(s): Christophe Piveteau, Christopher T. Chubb, and Joseph M. Renes By expanding tensor-network decoding capabilities to 3D codes, highly accurate decoders that outperform the state of the art are demonstrated for quantum error correction.

  • Weight-Reduced Stabilizer Codes with Lower Overhead

    Author(s): Eric Sabo, Lane G. Gunderman, Benjamin Ide, Michael Vasmer, and Guillaume Dauphinais A simple weight-reduction method that preserves the number of logical qubits and often increases the code distance is proposed for small-to-medium-sized quantum low-density parity-check codes.

  • Non-Abelian Transport Distinguishes Three Usually Equivalent Notions of Entropy Production

    Author(s): Twesh Upadhyaya, William F. Braasch, Jr., Gabriel T. Landi, and Nicole Yunger Halpern Three equivalent formulas for classical stochastic entropy production become inequivalent in the quantum domain, revealing new facets of entropy production for quantum systems.
