Figure 2From: Quantum encryption of superposition states with quantum permutation pad in IBM quantum computersA sample decryption circuit of a ciphertext block being decrypted with QPP using Qiskit on an IBM Quantum system. The initialization operator produces an initial state vector that corresponds to a given specified binary string. The Hermitian conjugate of the Permutation Operator decrypts the state vector to produce a message state, which is then measured. This illustration corresponds to our previous work [25, 26]Back to article page
