| Abstract: | 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 decoherence of quantum bit is studied. |

| Keywords: | degenerate two photon thermal radiation field two level atom quantum bit decoherence. |
