Implementation of controlled SWAP gates for quantum fingerprinting and photonic quantum computation
B. Wang, L. -M. Duan
Abstract
We propose a scheme to implement quantum controlled SWAP gates by directing single-photon pulses to a two-sided cavity with a single trapped atom. The resultant gates can be used to realize quantum fingerprinting and universal photonic quantum computation. The performance of the scheme is characterized under realistic experimental noise with the requirements well within the reach of the current technology.
