Leakage reduction in fast superconducting qubit gates via optimal control
Leakage reduction in fast superconducting qubit gates via optimal control
Abstract Reaching high-speed, high-fidelity qubit operations requires precise control over the shape of the underlying pulses. For weakly anharmonic systems, such as superconducting transmon qubits, short gates lead to leakage to states outside of the computational subspace. Control pulses designed with open-loop optimal control may reduce such leakage. However, model …
