Non-Holonomic Control III : Coherence Protection by the Quantum Zeno   Effect and Non-Holonomic Control
  In this paper, we present a coherence protection method based upon a multidimensional generalization of the Quantum Zeno Effect, as well as ideas from the coding theory. The non-holonomic control technique is employed as a physical tool which allows its effective implementation. The two limiting cases of small and large quantum systems are considered.
