Résumé : We present a family of loss-tolerant quantum strong-coin-flipping protocols, each protocol differing in the number of qubits employed. For a single qubit we obtain a bias of 0.4, reproducing the result of Berlín et al. [Phys. Rev. A 80, 062321 (2009)], while for two qubits we obtain a bias of 0.3975. Numerical evidence based on semidefinite programming indicates that the bias continues to decrease as the number of qubits increases but at a small rate. © 2010 The American Physical Society.
