Abstract

We present a scheme to study non-Abelian adiabatic holonomies for open Markovian systems. As an application of our framework, we analyze the robustness of holonomic quantum computation against decoherence. We pinpoint the sources of error that must be corrected to achieve a geometric implementation of quantum computation completely resilient to Markovian decoherence.

摘要

我们提出了一种研究开放马尔可夫系统中非阿贝尔绝热全同伦的方案。作为我们框架的一个应用，我们分析了全同伦量子计算对退相干的鲁棒性。我们确定了为实现完全抗马尔可夫退相干的量子计算几何实现而必须纠正的误差来源。
