    "abstract": "By using local quantum teleportation of a fixed state to one qubit of an\nentangled pair sent from the other party, it is shown how one party can commit\na bit with only classical information as evidence that results in an\nunconditionally secure protocol. The well-known ``impossibility proof\u0027\u0027 does\nnot cover such protocols due to its different commitment and opening\nprescriptions, which necessitate actual quantum measurements among different\npossible systems that cannot be entangled as a consequence.",
