在腔QED中实现Deutsh—Jozsa算法的可行方案

Realization of Deutsh-Jozsa Algorithm in Cavity QED

提出一个在腔QED中实现Deutsh-Jozsa算法的可行方案．此方案不需要原子与腔之间的信息转换。腔场实际上只是被激发。大幅度降低了对腔的品质要求．

A practical protocol is proposed for realizing Deutsh-Jozsa algorithm in cavity QED. The scheme does not require the transfer of quantum information between the atoms and cavity. In the scheme the cavity is only virtually excited, so the requirement on the quality of the cavity is greatly loosened.
