    "abstract": "In the literature, strong coin tossing protocols based on bit commitment have\nbeen proposed. Here we examine a protocol that instead tries to achieve the\ntask by sharing entanglement securely. The protocol uses only qubits, and has\nbias 1/4. This is equal to the best known bias for bit commitment based\nschemes.",
