我们给出了一类特定的非阿贝尔完整量子门的鲁棒性的数值研究。我们考虑了由于控制场的随机波动引起的参数噪声，这些噪声驱动时相关的哈密顿量沿绝热回路运动。使用的性能估计器是无噪声和有噪声完整门之间的状态保真度。我们用不同的相关时间进行分析，我们发现在“短”和“长”噪声相关时间下，有噪声的完整门似乎与无噪声的完整门接近。这个结果可以解释为完整算子的几何性质的结果。我们的模拟是通过使用与激子方案相关的参数来实现完整量子计算的[P]。Solinas et al.，物理学。[j].生物工程学报，2014,27(3)。
We present a numerical study of the robustness of a specific class of non-Abelian holonomic quantum gates. We take into account the parametric noise due to stochastic fluctuations of the control fields which drive the time-dependent Hamiltonian along an adiabatic loop. The performance estimator used is the state fidelity between noiseless and noisy holonomic gates. We carry over our analysis with different correlation times and we find out that noisy holonomic gates seem to be close to the noiseless ones for 'short' and 'long' noise correlation times. This result can be interpreted as a consequence of the geometric nature of the holonomic operator. Our simulations have been performed by using parameters relevant to the excitonic proposal for the implementation of holonomic quantum computation [P. Solinas et al., Phys. Rev. B 67, 121307 (2003)].
