An Entanglement-Based Protocol For Strong Coin Tossing With Bias 1/4
arXiv:quant-ph/0609034 · doi:10.1016/j.physleta.2006.10.062
Abstract
In the literature, strong coin tossing protocols based on bit commitment have been proposed. Here we examine a protocol that instead tries to achieve the task by sharing entanglement securely. The protocol uses only qubits, and has bias 1/4. This is equal to the best known bias for bit commitment based schemes.
