Author(s): Hsiang-Ku Lin, Pak Kau Lim, Alexey A. Kovalev, and Leonid P. Pryadko A new family of quantum low-density parity-check codes, which are locally equivalent to higher-dimensional hypergraph-product codes, achieves single-shot fault tolerance and an approximately 1.1% pseudothreshold with significantly shorter block lengths.

Author(s): Alexander Cowtan, Zhiyang He, Dominic J. Williamson, and Theodore J. Yoder Performance of many parallel measurements on quantum low-density parity-check codes, a key capability for protecting quantum memories during computation, is achieved in a new scheme that preserves important code properties without requiring additional code blocks.

Author(s): Joseph D. Broz, Jesse C. Hoke, Edwin Acuna, and Jason R. Petta By tuning the pairwise exchange interactions between three exchange-coupled electrons to be exactly equal, an energy gap between the computational subspace and extraneous levels is created, suppressing leakage errors.

Author(s): Sayan Chakraborty and Victor V. Albert Combinations of discrete- and continuous-variable systems are brought into the stabilizer formalism with new classes of stabilizer states and scalable error-correcting codes and could improve displacement sensing protocols.
