    "abstract": "We study the potential of general quantum operations, Trace-Preserving\nCompletely-Positive Maps (TPCPs), as encoding and decoding mechanisms in\nquantum authentication protocols. The study shows that these general operations\ndo not offer significant advantage over unitary encodings. We also propose a\npractical authentication protocol based on the use of two successive unitary\nencodings.",
