Claim 0:
1. A method of correcting light-shift effects on a single qubit gate, comprising:
applying a pair of Raman laser beams to single trapped ions in a trapped ion chain used for the single qubit gate;
determining one or more parameters that describe a relationship between a gain factor of one of the Raman laser beams and a light-shift effect that causes a change in resonance of qubit states of the single qubit gate by coupling of the qubit states to other states of the single qubit gate; and
dynamically adjusting a gain and a frequency of a radio frequency (RF) source for the one Raman laser beam based on the one or more parameters to correct for dephasing errors in the single qubit gate caused by the change in the resonance of the qubit states.
