Learning unknown stabilizer codes using product measurements
Researchers have introduced an algorithm for learning the stabilizer generators of an unknown stabilizer code using random single-qubit measurements. The method is aimed at improving the characterization of quantum error-correcting codes, which is needed for fault-tolerant quantum computation.

If the algorithm performs as claimed, it could enable experimental groups to verify and debug stabilizer codes using only product measurements, simplifying the characterization of logical qubits on current hardware.
Product measurements are widely available in superconducting and trapped-ion systems; avoiding entangled measurements lowers the experimental overhead for characterizing unknown codes. The preprint's algorithm still needs peer review and empirical testing.
