  At present, several models for quantum computation have been proposed.
Adiabatic quantum computation scheme particularly offers this possibility and
is based on a slow enough time evolution of the system, where no transitions
take place. In this work, a new strategy for quantum computation is provided
from the opposite point of view. The objective is to control the non-adiabatic
transitions between some states in order to produce the desired exit states
after the evolution. The model is introduced by means of an analogy between the
adiabatic quantum computation and an inelastic atomic collision. By means of a
simple two-state model, several quantum gates are reproduced, concluding the
possibility of diabatic universal fault-tolerant quantum computation. Going a
step further, a new quantum diabatic computation model is glimpsed, where a
carefully chosen Hamiltonian could carry out a non-adiabatic transition between
the initial and the sought final state.
