Computational geometry is the art of designing efficient algorithms for answering geometric questions. Computational geometry involves efficient and elegant solutions for difficult algorithmic problems and plays a central role in many different areas of computer science. Quantum cloning-based attacks have deep relevance to quantum cryptography. In this paper, the authors use the results of classical computational geometry to analyze the security of a quantum channel using current classical computer architectures. To analyze a quantum channel for a large number of input quantum states with classical computer architectures, very fast and effective algorithms are required.
