Considerations on Quantum-Based Methods for Communication Security
It offers an intuitive-level discussion for researchers and practitioners in communication security, but it is incremental as it focuses on exposition rather than new results.
The paper discusses the challenges and opportunities of quantum-based methods for secure communications, aiming to provide a clear foundation for assessing their potential value compared to classical alternatives.
In this paper we provide an intuitive-level discussion of the challenges and opportunities offered by quantum-based methods for supporting secure communications, e.g., over a network. The goal is to distill down to the most fundamental issues and concepts in order to provide a clear foundation for assessing the potential value of quantum-based technologies relative to classical alternatives. It is hoped that this form of exposition can provide greater clarity of perspective than is typically offered by mathematically-focused treatments of the topic. It is also hoped that this clarity extends to more general applications of quantum information science such as quantum computing and quantum sensing.
