Fast and robust two-qubit gates for scalable ion trap quantum computing
J. J. Garcia-Ripoll, P. Zoller, J. I. Cirac
Abstract
We propose a new concept for a two-qubit gate operating on a pair of trapped ions based on laser coherent control techniques. The gate is insensitive to the temperature of the ions, works also outside the Lamb-Dicke regime, requires no individual addressing by lasers, and can be orders of magnitude faster than the trap period.
