Macroscopic resonant tunneling (MRT) in flux qubits is an importantexperimental tool for extracting information about noise produced by a qubit'ssurroundings. Here we present a detailed derivation of the MRT signal in theRF-SQUID flux qubit allowing for effects of flux and charge fluctuations on theinterwell and intrawell transitions in the system. Taking into considerationtransitions between the ground state in the initial well and excited states inthe target well enable us to characterize both flux and charge noise sourceaffecting the operation of the flux qubit. The MRT peak is formed by thedominant noise source affecting specific transition, with flux noisedetermining the lineshape of the ground to ground tunneling, whereas chargenoise reveals itself as additional broadening of the ground to excited peak.
