| Abstract: | A scheme is suggested for the generation of multi-atom maximally entangled states with a cavity in a thermal state. In this scheme several
appropriately prepared two-level atoms are simultaneously sent through the
nonresonant cavity. We divide the whole atom-cavity interaction time into
two equal parts. At the end of the first part a π pulse is applied to
the atoms using a classical field. Then the photon-number-dependent shifts
on the atomic states are cancelled and the atomic system finally evolves to
a maximally entangled state. |
