Control of Superconducting Qubits

In superconducting quantum computing, precise control of qubit dynamics is crucial for achieving high-fidelity gate operations. One of the key challenges arises from the multilevel nature of transmon qubits, which can lead to leakage out of the computational subspace. To address this issue, the derivative removal by adiabatic gate (DRAG) technique has been proposed and extensively studied. In this presentation, we provide a theoretical overview of the DRAG method and its extensions to both qubit and qutrit systems. We show how properly shaped control pulses, including derivative components, can effectively suppress leakage and phase errors during gate implementation.
