Towards Secure Classical-Quantum Systems

Quantum computing has emerged as a promising paradigm, offering significant advancements in solving complex problems that are intractable for classical computers. These systems often involve integrated classical-quantum architectures, where classical components control and communicate with quantum devices. While this integration unlocks the potential of quantum computing, it also introduces new security vulnerabilities and challenges that must be addressed to ensure secure and reliable classical-quantum computing. This paper provides a comprehensive overview of the security concerns related to classical-quantum systems and discusses potential countermeasures. Specifically, we first investigate secure communication with a quantum device through side-channel analysis of post-quantum encryption algorithms. Next, we analyze security vulnerabilities in quantum devices. Finally, we explore mitigation strategies as well as the role of quantum compilation for securing quantum devices. By examining and addressing these critical security concerns, we aim to contribute to the development of a secure and robust foundation for the future of quantum computing. This work will be a stepping stone in secure and trustworthy deployment of integrated classicalquantum systems across various application domains.
