Abstract A scheme is proposed to implement a universal quantum cloning machine with atoms trapped in an optical cavity. In the scheme the atoms are always populated in the two ground states and the cavity remains in the vacuum state. Therefore, the scheme is insensitive to the atomic spontaneous emission and cavity decay.
