From: Deterministic generation of two-dimensional multi-photon cluster states

Fig. 3

Phase of the experimental ρExp (below diagonal) and the ideal ρIdeal (above diagonal) density matrix of the 20 qubit cluster state, showing only (a) the upper-left part and b far off-diagonal part of the full density matrix. Darker colored triangles in the insets indicate the sections of the density matrix displayed.
