Abstract
The present disclosure relates to a quantum error correction code and, more particularly, to a method and apparatus for optimizing a quantum error correction code in biased error environment. The method for optimizing a quantum error correction code, according to an embodiment of the present disclosure, may comprise the steps of: estimating, on the basis of a physical error rate (p) and a bias degree (η), a logical error rate (P) for each of one or more candidate lattice sizes; determining, on the basis of the estimated logical error rate (P) and a target logical error rate (P), an optimal lattice size from among the one or more candidate lattice sizes; and arranging a Qubit on the basis of the optimal lattice size. Here, when the bias degree (η) exceeds 1, the one or more candidate lattice sizes may be defined in the form of a rectangular excluding a square.
