Clustered Error Correction of Codeword-Stabilized Quantum Codes
Yunfan Li, Ilya I. Dumer, Leonid P. Pryadko · Physical Review Letters · 2010
Codeword-stabilized codes are a general class of quantum codes that includes stabilizer codes and many families of nonadditive codes with good parameters. For such a nonadditive code correcting all t-qubit errors, we propose an algorithm that employs a single measurement to test all errors located on a given set of t qubits. Compared with exhaustive error screening, this reduces the total number of measurements required for error recovery by a factor of about 3(t).
