- Abstract: Advanced Encryption Standard (AES) is one of the most widely used and extensively studied encryption algorithms globally, which is renowned for its efficiency and robust resistance to attacks. In this paper, three quantum circuits are designed to implement the S-box, which is the sole nonlinear component in AES. By incorporating a linear key schedule, we achieve a quantum circuit for implementing AES with the minimum number of qubits used. As a consequence, only 264/328/398 qubits are needed to implement the quantum circuits for AES-128/192/256. Furthermore, through quantum circuits of the S-box and key schedule, the overall size of the quantum circuit required for Grover's algorithm to attack AES is significantly decreased. This enhancement improves both the security and resource efficiency of AES in a quantum computing environment.
