Entangling ions in arrays of microscopic traps
Tommaso Calarco, J. I. Cirac, P. Zoller · Physical Review A · 2001
We consider a system of particles in an array of microscopic traps, coupled to each other via electrostatic interaction, and pushed by an external state-dependent force. We show how to implement a two-qubit quantum gate between two such particles with a high fidelity.
