RT Journal Article T1 Quantum-state preparation and control via the Zeno effect A1 Luis Aina, Alfredo AB We present different schemes for preparing and maintaining the quantum state of multilevel systems. This is achieved via a suitable combination of coherent trapping and the Zeno effect which serves to protect the prepared state against undesired jumps to other states.
