Abstract
Systems and techniques that facilitate Stark shift cancellation are provided. In various embodiments, a system can comprise a control qubit that is coupled to a target qubit. In various cases, the control qubit can be driven by a first tone that entangles the control qubit with the target qubit. In various aspects, the control qubit can be further driven by a second tone simultaneously with the first tone. In various cases, the second tone can have an opposite detuning sign than the first tone. In various instances, the first tone can cause a Stark shift in an operational frequency of the control qubit, and the second tone can cancel the Stark shift.
