Abstract
We have performed spectroscopy measurements on two coupled flux qubits. The qubits are coupled inductively, which results in a σ1zσ2z interaction. By applying microwave radiation, we observe resonances due to transitions from the ground state to the first two excited states. From the position of these resonances as a function of the applied magnetic field, we observe the coupling of the qubits. The coupling strength agrees with calculations of the mutual inductance.
