两能级原子置于外部环境(热库)时，将两能级原子视为量子位，通过分析简并双光子过程中量子位约化密度算符非对角元的时间演化，研究量子位消相干规律。

The two-level atom is regarded as quantum-bit when the two-level atom is put in a thermal reservoir.The time evolution properties of non-opposite angle element of quantum-bit's reducible density rectangular array is discussed and decohere...
