两原子纠缠态的制备

Generation of Two-Atom Entangled States

提出一种基于原子与腔场共振相互作用的制备两原子纠缠态的方案．在本方案中，两个双能级原子以很快的速度穿过一个初始处于真空态的腔，然后第３个原子以很快的速度穿过这个腔．

A scheme is proposed for preparing two-atom entangled states. It is based on resonant interaction of atoms with a field. In the scheme two two-level atoms pass through an initially empty cavity with a high velocity. Then a third atom is sent through the cavity. The detection of the third atom projects the first two atoms onto an entangled state.
