| Abstract: | A scheme is presented for realizing quantum logic gates for two
atoms localized in two distant optical cavities. Our scheme works in
a regime in which the atom--cavity coupling strength is smaller
than the cavity decay rate. Thus the requirement on the quality
factor of the cavities is greatly relaxed. Furthermore, the fidelity
of our scheme is not affected by detection inefficiency and
atomic decay. These advantages are important in view of experiment. |
