Fault-tolerant quantum computation with asymmetric Bacon-Shor codes
Fault-tolerant quantum computation with asymmetric Bacon-Shor codes
We develop a scheme for fault-tolerant quantum computation based on asymmetric Bacon-Shor codes, which works effectively against highly biased noise dominated by dephasing. We find the optimal Bacon-Shor block size as a function of the noise strength and the noise bias, and estimate the logical error rate and overhead cost …
