We consider a system consisting of a large number of interacting qubits and study the geometric phase of one of them. The many body interaction is analyzed within a mean-field approach when the reduced dynamics of a single qubit is described by a nonlinear Hartree equation. Generally, the geometric phase is highly sensitive to the type and the strength of interaction. However, we identify regimes where the geometric phase is almost independent of the qubit-qubit coupling.
