量子比特系统中1/f噪声过程的动力学抑制

Dynamical suppression of 1/f noise processes in qubit systems

Lara Faoro, Lorenza Viola

摘要:

我们调查的能力,动态解耦技术,以减少从现实环境中产生1/f噪声的退相干。噪声分布中低频模式的优势允许去相干场景,其中相对较慢的控制速率足以实现大幅改善。然而,实际的品质因数对动态特性的细节非常敏感,解耦性能可能会因非高斯噪声和/或高频工作点而恶化。我们的结果是有希望的强大的固态量子比特和超越。

英文摘要:

We investigate the capability of dynamical decoupling techniques to reduce decoherence from a realistic environment generating 1/f noise. The predominance of low frequency modes in the noise profile allows for decoherence scenarios where relatively slow control rates suffice for a drastic improvement. However, the actual figure of merit is very sensitive to the details of the dynamics, with decoupling performance which may deteriorate for non-Gaussian noise and/or high frequency working points. Our results are promising for robust solid-state qubits and beyond.
