Figure 4From: Quantum encryption with quantum permutation pad in IBMQ systemsThe Quantum Permutation Pad in the case of ideal fully-quantum permutation will be applied as one pad to plaintetx qubits. For this specific illustration each permutation in the permutation pad acts on 2 qubits simultaneously. Permutation operators are not limited to 2 qubits at a time, however, we depict it for the sake of simplicity without loss of generality using 2-qubits permutationsBack to article page
