Figure 3: Experimental data from the characterization and performance of perfect state transfer waveguide array.
From: Experimental perfect state transfer of an entangled photonic qubit
(a–c) Propagation simulations showing the device implementation to enable specific waveguide input. (d–f) Output probability distributions for each input of the PST array for horizontally and vertically polarized laser light. (g–i) Quantum process matrix for each transfer in the PST array measured with single-photon quantum process tomography. (j–l) Two-photon quantum state tomography is performed after photon 1 of the polarization entangled Bell state 
has been relocated. Results have had the small imaginary components removed for brevity.
