Fluxon readout for superconducting flux qubits

Fedorov, Kirill

Abstract:
This thesis presents experimental studies on developing of a novel fluxon readout for superconducting flux qubits. It is based on a scheme for detecting the microwave radiation of an oscillating fluxon in an annular Josephson junction (AJJ). The readout was implemented for a superconducting flux qubit coupled as a current dipole to the AJJ. An energy spectrum of the flux qubit was measured via detecting a frequency shift of the fluxon oscillations versus a flux bias through the qubit.
