    "abstract": "We demonstrate a simple technique to prepare and determine the desired\ninternal quantum states in multi-Zeeman-sublevel atoms. By choosing appropriate\ncoupling and pumping laser beams, atoms can be easily prepared in a desired\nZeeman sublevel with high purity or in any chosen ground-state population\ndistributions. The population distributions or state purities of such prepared\natomic states can be determined by using a weak, circularly-polarized probe\nbeam due to differences in transition strengths among different Zeeman\nsublevels. Preparing well-defined internal quantum states in\nmulti-Zeeman-sublevel atoms (or spin-polarized quantum-state engineering) will\nbe very important in demonstrating many interesting effects in quantum\ninformation processing with multi-level atomic systems.",
