  We propose a quantum state readout mechanism of a weakly coupled qubit in
dispersive regime. The hybrid system consists of ferromagnetic insulator and a
superconducting qubit in a microwave cavity. The enhancement of the measurement
sensitivity is achieved by exerting torque on the ferromagnetic insulator
magnetization, which compensates the damping of the system leading to an
exceptional point. The proposed machanism allows to measure the qubit state
either via the transmission of the cavity or the FMR signal of the magnetic
material.
