General error-transparent quantum gates for fault-tolerant quantum computation

ORAL

Abstract

Error-transparent (ET) quantum gates have recently been proposed for small logical qubit architectures [arXiv:1703.09762]. The key idea is to design the Hamiltonian evolution for an ET logical quantum gate, so that it commutes with all first order error processes which may occur anytime during the evolution. Even if the error occurs in the mid of the evolution, it will be detected/corrected at the end of the evolution without compromising the encoded quantum information. We provide a general construction of ET logical quantum gates for any quantum error correction code. In addition, we investigate practical implementation of ET logical quantum gates with circuit QED systems.
