From: Faithful conditional quantum state transfer between weakly coupled qubits

The reconstructed channel matrices χ are plotted for ω = 55° and for three scenarios: (a) both filtering and feed-forward switched off, (b) filter set on but feed-forward switched off and (c) full implementation with both quantum filter and feed-forward on. The first and the second row show the real and imaginary parts of the reconstructed matrix, respectively. For ease of comparison, all matrices are normalized such that Tr(χ) = 1.
