MAXIMALLY ENTANGLED STATES FOR MANY TRAPPED IONS FROM SINGLE RESONANT INTERACTIONS
Lin Li, Dahai Xu, Yonghong Tian, Xiuhua Yuan · International Journal of Modern Physics B · 2007
We propose an alternative scheme to generate the GHZ states and cluster states for many trapped ions illuminated by a single laser tuned to the first lower vibrational sideband. The distinct advantage of the present scheme is that it does not use the vibrational mode as the data bus and only requires a single resonant interaction. Thus the present scheme is very simple and the interaction time is very short, which is important in view of decoherence.
