We show that an $LC$ parametric transducer can be effectively used to monitor an adiabatic evolution of the superconducting flux qubit. We propose a new scheme to measure the qubit's state, which is a quantum nondemolition measurement. The scheme, which can be easily extended to a three-qubit system, allows the reading out the qubits' states while remaining in the ground state of the system. An implementation of the adiabatic quantum algorithm MAXCUT for three superconducting flux qubits is discussed.
