非阿贝尔几何相位由于在量子计算中可能的实验应用而引起人们越来越多的兴趣。我们研究的环境（建模为一个合奏的谐振子）的完整变换的影响，并写相应的主方程。的解决方案进行了分析和数值研究和保真度分析的行为：保真度复兴观察和确定的最佳有限的操作时间，在该门是最强大的对噪声。
Non-Abelian geometric phases are attracting increasing interest because of possible experimental application in quantum computation. We study the effects of the environment (modeled as an ensemble of harmonic oscillators) on a holonomic transformation and write the corresponding master equation. The solution is analytically and numerically investigated and the behavior of the fidelity analyzed: fidelity revivals are observed and an optimal finite operation time is determined at which the gate is most robust against noise.
