Review of vulnerabilities in quantum hardware

Abstract As quantum systems move towards practical deployment, there is a need to prioritize research focused on security risks and mitigation strategies. This paper presents the current literature on vulnerabilities in different hardware implementations of quantum computers and categorizes vulnerabilities based on underlying qubit technology. The review also examines attack methodology, source, impact and mitigation strategies for two types of hardware vulnerabilities: crosstalk and side channel attacks. The aim of this paper is to provide an understanding of the evolution of quantum vulnerability research at hardware level and to highlight the need to implement security into the design of quantum computers from its early stages.
