    "abstract": "This paper describes how to perform contract signature in a fair way using\nquantum information. The protocol proposed permits two partners, users of a\ncommunication network, to perform a contract signature based on the RSA\nsecurity. The authentication of the signers is based on the use of a non-local\nXOR function of two classical bits.",
