    "abstract": "We review the quantum version of a well known problem of cryptography called\ncoin tossing (``flipping a coin via telephone\u0027\u0027). It can be regarded as a game\nwhere two remote players (who distrust each other) tries to generate a\nuniformly distributed random bit which is common to both parties. The only\nresource they can use to perform this task is a classical or quantum\ncommunication channel. In this paper we provide a general overview over such\ncoin tossing protocols, concerning in particular their security.",
