One-step implementation of the genuine Fredkin gate in high-Q coupled three-cavity arrays
One-step implementation of the genuine Fredkin gate in high-Q coupled three-cavity arrays
We present two efficient methods for implementing the Fredkin gate with atoms separately trapped in an array of three high-$Q$ coupled cavities. The first proposal is based on the resonant dynamics, which leads to a fast resonant interaction in a certain subspace while leaving others unchanged, and the second one …
