    "abstract": "We study the role of discrete rotational symmetry in quantum key distribution\nby generalizing the well-known Bennett-Brassard 1984 (BB84) and\nScarani-Acin-Ribordy-Gisin 2004 (SARG04) protocols. We observe that discrete\nrotational symmetry results in the protocol\u0027s invariance to continuous\nrotations, thus leading to a simplified relation between bit and phase error\nrates and consequently a straightforward security proof.",
