Engineering Tripartite Entangled States of Two Phase Qubits Coupled via a Cavity

We present an experimentally inexpensive scheme for preparing certain tripartite entangled states. We suggest ways to test the degree to which such target states have been successfully prepared. We present a convenient geometrical interpretation of the resonant unitary dynamics which gives a natural interpretation for the characteristic frequencies and provides intuition for the pulse sequence necessary to achieve a desired target state.
