Claim 10:
11. A method of correcting light-shift effects on a two-qubit gate, comprising:
applying a pair of Raman laser beams to each trapped ion used for a qubit in the two-qubit gate;
determining for each qubit in the two-qubit gate, a single parameter that describes a relationship between a gain factor of one of the Raman laser beams applied to the respective trapped ion of the qubit and a light-shift effect that causes a change in resonance of the qubit states of the qubit by coupling of the qubit states with other states of the qubit; and
dynamically adjusting for each qubit in the two-qubit gate, a gain and a frequency of a radio frequency (RF) source for the one Raman laser beam applied to the respective trapped ion of the qubit based on the single parameter to correct for dephasing errors in the two-qubit gate caused by the change in the resonance of the qubit states in each qubit in the two-qubit gate.
