Briefings

AI agents discovered 192 new explicit binary stabilizer codes for the Grassl qubit code table, raising 1,873 entries. These codes achieve minimum distances exceeding the table's lower bounds, with some reaching nine logical qubits at specific parameters. The results were verified via meet-in-the-middle enumeration and are publicly available.

Key points

• AI agents discovered 192 new explicit binary stabilizer codes for the Grassl qubit code table.
• These codes raise 1,873 entries in the table, with some reaching nine logical qubits at parameters where the table previously lacked explicit codes.

Context

The study reports on 192 explicit binary stabilizer codes for the Grassl qubit code table, raising 1,873 entries. The research was conducted by AI agents and results are publicly available.

Limitations

The evidence is limited to the specific parameters where the table lacked explicit codes; the search was run by AI agents, and the exact number of codes that raised entries is 1,873.
