In addition to magnetic field and electric charge noise adversely affectingspin qubit operations, performing single-qubit gates on one of multiple coupledsinglet-triplet qubits presents a new challenge---crosstalk, which isinevitable (and must be minimized) in any multiqubit quantum computingarchitecture. We develop a set of dynamically-corrected pulse sequences thatare designed to cancel the effects of both types of noise (i.e., field andcharge) as well as crosstalk to leading order, and provide parameters for thesecorrected sequences for all 24 of the single-qubit Clifford gates. We thenprovide an estimate of the error as a function of the noise and capacitivecoupling to compare the fidelity of our corrected gates to their uncorrectedversions. Dynamical error correction protocols presented in the current workare important for the next generation of singlet-triplet qubit devices wherecoupling among many qubits will become relevant.
