    "abstract": "We present an analysis of spontaneous emission in a 3-level atom as an\nexample of a qutrit state under the action of noisy quantum channels. We choose\na 3-level atom with V-configuration to be the qutrit state. Gell-Mann matrices\nand a generalized Bloch vector (8-dimensional) are used to describe the qutrit\ndensity operator. Using the time-evolution equations of atomic variables we\nfind the Kraus representation of spontaneous emission quantum channel (SE\nchannel). Furthermore, we consider a generalized Werner state of two qutrits\nand investigate the separability condition. We give similar analysis of\nspontaneous emission for qubit channels. The influence of spontaneous emission\non the separability of Werner states for qutrit and qubit states is compared.",
