      abstract     = {Electron paramagnetic resonance experiments show that the
                      decay of Rabi oscillations of ensembles of spin qubits
                      depends noticeably on the microwave power, and more
                      precisely on the Rabi frequency, an effect recently called
                      "driven decoherence." By direct numerical solution of the
                      time-dependent Schrodinger equation of the associated
                      many-body system, we scrutinize the different mechanisms
                      that may lead to this type of decoherence. Assuming the
                      effects of dissipation to be negligible (T-1 = infinity), it
                      is shown that a system of dipolar-coupled spins with (even
                      weak) random inhomogeneities is sufficient to explain the
                      salient features of the experimental observations. Some
                      experimental examples are given to illustrate the potential
                      of the numerical simulation approach.},
