One step to generate quantum controlled phase-shift gate using a trapped ion
Zhang Shi-jun, Chi Ma, Wen‐Hai Zhang, Ye Liu · Chinese Physics B · 2008
This paper presents a very simple scheme for generating quantum controlled phase-shift gate with only one step by using the two vibrational modes of a trapped ion as the two qubits. The scheme couples two vibration degrees of freedom coupled with a suitable chosen laser excitation via the ionic states.
