    "abstract": "In this letter we present the first implementation of a quantum coin tossing\nprotocol. This protocol belongs to a class of ``two-party\u0027\u0027 cryptographic\nproblems, where the communication partners distrust each other. As with a\nnumber of such two-party protocols, the best implementation of the quantum coin\ntossing requires qutrits. In this way, we have also performed the first\ncomplete quantum communication protocol with qutrits. In our experiment the two\npartners succeeded to remotely toss a row of coins using photons entangled in\nthe orbital angular momentum. We also show the experimental bounds of a\npossible cheater and the ways of detecting him.",
