Abstract: Quantum circuits serve as the core carriers of quantum information, and their stability and reliability directly determine practical deployment of quantum computing and quantum communication systems. To address the lack of security protection during quantum circuit compilation in quantum cloud computing scenarios, this paper proposes a secure compilation scheme based on quantum power function obfuscation for quantum cloud computing. By leveraging the characteristics of quantum cloud computing and quantum cryptographic protocols, the scheme can protect the compilation process of quantum circuits. Specifically, by utilizing quantum obfuscation techniques, the scheme enables key agreement between the client and the quantum cloud platform. And the sensitive quantum circuit information is protected via key-based obfuscation circuits which employ quantum homomorphic encryption methods, thereby enhancing the security of the compilation process of quantum circuits. Experimental results demonstrate that the scheme can effectively obfuscate quantum circuit functionalities, ensuring that quantum circuits can be executed correctly only upon provision of a valid key.
