Abstract
The performance of a quantum feedback loop designed to maintain a desired phase of quantum coherent oscillations in a single solid-state qubit is analyzed using the quantum Bayesian formalism. The degree of oscillations synchronization with classical reference signal is calculated as a function of feedback strength, taking also into account finite detector bandwidth, dephasing due to environment, and qubit energy asymmetry.
