Scalable defect-based solid-state quantum devices

• Speaker: Lee, Sangyun (KIST)

Here we introduce our recent work on the all-microwave scheme for the controlled-NOT (cNOT) gate between two superconducting transmon qubits. We constructed cNOT gate based on the microwave-activated phase (MAP) gate, with phase compensation by Z-axis phase gates using microwave hyperbolic secant pulses. We present advantages and limitations of this method, together with the brief analysis of sources of errors.
