In this talk, we present examples of the challenges of realistic device simulations, going beyond standard Markovian noise models. We start with the triple-dot decoherence-free-subspace qubit, where one qubit is comprised of three quantum dots. In this system, only native ‘gate’, exchange between neighboring quantum dots, is used to compile all qubit operations. Noise in these systems is typically highly non-Markovian, comprising both leakage and 1/f qualities. Even with these challenges, accurate simulations can be performed and compare favorably with experiment. Time permitting, we will also discuss pulse design in neutral atom qubits using realistic device simulations.
