摘要

我们设计了灵活的容错门小工具，允许使用不同的代码对数据和ancilla进行编码。通过为ancilla选择稳定器代码，我们能够在通用量子代码（包括稳定器代码和非增量代码）上执行克利福德和非克利福德容错门。这使我们能够展示首个针对非加法码的通用容错门集。我们同时考虑了相消信道和去极化信道的容错问题。

Flexible Fault Tolerant Gate Gadgets

We design flexible fault tolerant gate gadgets that allow the data and the ancilla to be encoded using different codes. By picking a stabilizer code for the ancilla we are able to perform both Clifford and non-Clifford gates fault tolerantly on generic quantum codes, including both stabilizer and non-additive codes. This allows us to demonstrate the first universal fault tolerant gate set for non-additive codes. We consider fault tolerance both with respect to a dephasing channel and a depolarizing channel.
