We have discovered that, in specific cases, decoherence due to the interaction with the environment can be avoided by just introducing a special driving field for an open quantum system. We show that this phenomenon constitutes a new class of decoherence‐free subspaces which are useful for passive preservation of quantum information and discuss a physical example.
