We investigate the possibility to restore particle number in many-body dynamical problems by mixing-up several Time-Dependent Hartree-Fock Bogolyubov (TDHFB) trajectories. In our approach, each trajectory is independent from the others and the quantum mixing between trajectories is deduced from a variational principle.
