Zusammenfassung

Within the lowest-order Born approximation, we calculate the exact dynamics of a qubit in the presence of 1/f noise, without Markov approximation. We show that the non-Markovian qubit timeevolution exhibits asymmetries and beatings that can be observed experimentally and cannot be explained within a Markovian theory. The present theory for 1/f noise is relevant for both spin- and superconducting qubit realizations in solid-state devices, where 1/f noise is ubiquitous.
