Claim 5:
6. A quantum computer configured to correct light-shift effects on a single qubit gate, comprising:
a trap configured to hold a trapped ion chain;
an optical controller configured to apply a pair of Raman laser beams to single trapped ions in the trapped ion chain used for the single qubit gate; and
a general controller configured to determine 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,
wherein the optical controller is further configured to dynamically adjust 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.
