Figure 7

(Color online) Experimental results from the quantum state tomography procedure (real parts are shown, imaginary parts shown in the Appendix31).

(a) The initial state |ψ *〉. (b),(c) and (d) Three final states (equation (7)) for the cases, respectively, h = 0, h = 0.75hc and h = 1.25hc . (e),(f) and (g) The first 4 × 4 section of each density matrix above (after re-normalization), in the subspace where the probe qubit is projected to the |0〉 state.
