Between Shor and Steane: A Unifying Construction for Measuring Error Syndromes
Between Shor and Steane: A Unifying Construction for Measuring Error Syndromes
Fault-tolerant quantum error correction requires the measurement of error syndromes in a way that minimizes correlated errors on the quantum data. Steane and Shor ancilla are two well-known methods for fault-tolerant syndrome extraction. In this Letter, we find a unifying construction that generates a family of ancilla blocks that interpolate …
