Securing Quantum Computers: Safeguarding Against Eavesdropping and Side-Channel Attacks
Pranav Gani, Ross Greer · 2023
Methods of eavesdropping and side-channel attacks - physical attacks on cryptosystems - have always been developing to stay in the race against classical and even quantum security protocols. In this paper, we review foundational approaches to quantum security against such attacks. In particular, we examine principles of quantum mechanics which make security protocols such as quantum key distribution and BB84 possible. Further, we describe a variety of side-channel attack configurations and conclude by describing the relevance of these attacks and security measures across modern systems, motivating future research in quantum security.
