Construction of controlled-NOT gate based on microwave-activated phase (MAP) gate in two transmon system

Abstract We experimentally constructed an all-microwave scheme for the controlled-NOT (cNOT) gate between two superconducting transmon qubits in a three dimensional cavity. Our cNOT gate is based on the microwave-activated phase (MAP) gate, which requires an additional procedure to compensate the ac...
