The two emission steps

E1: explicit internal and emission Hamiltonians › The two emission steps · lines 563–577

Let $U_{int}$ be the ordered key preparation, dephasing, and controlled-Pauli sequence. The first emission step applies key emission and occupation emission $i = 1$ . The second applies ciphertext emission and occupation emission $i = 2$ . Within each step the two printed emission interactions commute.

Write

U^{(1)} = U_{num, 1} U_{1} U_{int}, U^{(2)} = U_{num, 2} U_{2} U^{(1)} .

$U^{(1)} = U_{num, 1} U_{1} U_{int}, U^{(2)} = U_{num, 2} U_{2} U^{(1)} .$
