Fig. 5: Fidelities of n-photon-added coherent states with exact coherent states.
From: Experimental preparation of multiphoton-added coherent states of light
Red solid lines represent the theoretical dependence of fidelity with the coherent state with amplitude βopt given by Eq. (11). Blue dashed lines depict theoretical fidelities with the coherent states with amplitude gn(α)α, where gn(α) is the amplification gain (7). Red circles and blue squares are the corresponding experimental fidelities determined from the reconstructed density matrices of the generated states. Data are plotted for n = 1 (a) and n = 2 (b).
