对于量子位的任意工作点，讨论了由于相关时间长于退相干时间的经典非高斯噪声导致的量子位的退相干。开发了一种方法，可以在存在独立随机电报噪声源的情况下导出相位记忆泛函的精确公式。
The decoherence of a qubit due to a classical non-Gaussian noise with correlation time longer than the decoherence time is discussed for arbitrary working points of the qubit. A method is developed that allows an exact formula for the phase-memory functional in the presence of independent random telegraph noise sources to be derived.
