摘要

En 中文

Quantum processors require Quantum Error Correction Codes (QECC & x2019;s) for improving the fidelity of quantum logic gates. Fault tolerant QECC & x2019;s are capable of providing error rate improvements in quantum processors as long as the components are operating below a certain gate error probability. In this contribution, we quantify the depolarization probability bound, below which transversal QECC & x2019;s would give a better error probability than an uncoded gate. Both a low-complexity repetition code and Steane & x2019;s 7-bit QECC are characterized.
