DYNAMIC REALIZATION OF QUANTUM MEASUREMENTS IN A QUANTIZED STERN-GERLACH EXPERIMENT

A novel dynamic model for wavefunction collapse in cavity quantum elec trodynamics (QED) is proposed associated with the gedanken Stem-Gerlac h experiment of the quantized magnetic field. It is used to describe a nd test the fundamental problems of quantum measurements, such as wave function collapse, Schrodinger entanglement states (cats) and quantum decoherence. This model also manifests rich phenomena in atomic optics , such as the splining of atomic beams, and the generation of even- an d odd-coherent states. It is also shown that this model possesses a fa ctorizable structure which has been found in the other dynamic models for wavefunction collapse.
