摘　　要：By using quantum bang-bang control technique,we studied the suppression of amplitude damping,or energy dissipation,in a three-level atom in various configurations.We have explicitly given the bang-bang control groups in three different configurations,and the pulse sequences for these bang-bang control operations.By using quantum bang-bang control technique, we studied the suppression of amplitude damping, or energy dissipation, in a three-level atom in various configurations.
