Abstract :
Summary form only given. Decoherence, i.e., the rapid destruction of the phase relation between two quantum states of a system caused by the entanglement of these two states with two different states of the environment, is the main limiting factor for quantum information processing. For this reason decoherence control is now becoming a rapidly expanding field of investigation. The progressive decoherence of a mesoscopic Schrodinger cat state has been observed for the first time in the experiment of Brune et al where the linear superposition of two coherent states of a field in a microwave cavity, with classically distinct phases, has been generated and detected.
