A controller of a quantum system causes performance of a single qubit gate on a target qubit. The controller causes a dressing field circuit to generate a dressing field at a target location where the target qubit is located. The dressing field modifies a set of initial states into a set of superposition states. A first (second) dressed state of the set of superposition states includes a non-zero contribution from a first (second) qubit state of the set of initial states. A dressed frequency difference between the first and second dressed states and a qubit frequency difference between the first and second qubit states are different. The controller causes a gate microwave signal characterized by the dressed frequency difference plus the qubit frequency difference to be incident on the target location. After a gate time, the controller controls operation of the dressing field circuit to stop generating the dressing field.
