This thesis demonstrates an entire Mach–Zehnder interferometer with interacting Bose–Einstein condensates restricted on an atom chip. It depends upon the coherent manipulation of atoms trapped in a magnetic double-well capability, for which the writer constructed a unique form of beam splitter. Particle-wave duality allows the development of interferometers for topic waves, which counterpoint optical interferometers in precision dimension units, either for technological functions and primary exams. This calls for the advance of atom-optics analogues to beam splitters, part shifters and recombiners.
Particle interactions within the Bose–Einstein condensate bring about a nonlinearity, absent in photon optics. this can be exploited to generate a non-classical country with lowered atom-number fluctuations contained in the interferometer. This nation is then used to review the interaction-induced dephasing of the quantum superposition. The ensuing coherence occasions are came across to be an element of 3 longer than anticipated for coherent states, highlighting the potential for entanglement as a source for quantum-enhanced metrology.
