ePrint Report: New record in the number of qubits for a quantum implementation of AES

Zhenqiang Li, Fei Gao, Sujuan Qin, Qiaoyan Wen

Optimizing the quantum circuit for implementing Advanced Encryption Standard (AES) is crucial for estimating the necessary resources in attacking AES by Grover algorithm. Previous studies have reduced the number of qubits required for the quantum circuits of AES-128/-192/-256 from 984/1112/1336 to 270/334/398, which is close to the optimal value of 256/320/384. It becomes a challenging task to …
