我们提出了一种在热腔中产生两个或多个多能级原子纠缠态的方案。在强经典场的辅助下，有效哈密顿量中的光子数相关部分被抵消。因此，该方案对腔体衰减和热场都不敏感。该方案不需要对空腔中的原子单独寻址。该方案也可用于产生许多热多能级离子的纠缠态。
We propose a scheme for generating entangled states for two or more multilevel atoms in a thermal cavity. The photon-number-dependent parts in the effective Hamiltonian are canceled with the assistance of a strong classical field. Thus the scheme is insensitive to both the cavity decay and the thermal field. The scheme does not require individual addressing of the atoms in the cavity. The scheme can also be used to generate entangled states for many hot multilevel ions.
