Creation of N-partite W-states by adiabatic passage and pulse area techniques

Abstract

We propose two relatively robust schemes to effectively generate controllable N-partite W states in atom-cavity-laser systems. In these schemes, we consider a situation where a traveling atom initially in the ground state, interacts simultaneously with the cavity-mode and the laser fields through stimulated Raman adiabatic passage and pulse area techniques in optical cavities. Losses due to atomic spontaneous emission are efficiently suppressed by employing appropriately designed atom-field couplings and suitable pulse ordering.
