Composable, unconditional security without a Quantum secret key: public broadcast channels and their conceptualizations, adaptive bit transmission rates, fidelity pruning under wiretaps
Pete Rigas
We examine public broadcast, forward conceptual, and backward conceptual, Quantum channels in the context of communication protocols that are independent of secret keys. Given rese…
Parallel repetition of expanded, and multiplayer, Quantum games: anchoring, optimal values, generalized error bounds, dependency-breaking as symmetry-breaking
Pete Rigas
We demonstrate that parallel repetition of the multiplayer anchored optimal value, , decays exponentially. Central to our approach are several pr…
Error correction, authentication, and false acceptance, probabilities for communication over noisy quantum channels: converse upper bounds on the bit transmission rate
Pete Rigas
We obtain strict upper bounds on the bit transmission rate for communication of Classical bit codewords over Quantum channels. Albeit previous arguments in arXiv: 1804.01797 which…
Quantum strategies, error bounds, optimality, and duality gaps for multiplayer XOR, , compiled XOR, , and strong parallel repetiton of XOR, , and FFL games
Pete Rigas
We characterize exact, and approximate, optimality of games that players can interact with using quantum strategies. In comparison to a previous work of the author, arXiv: 2311.128…
Exact solvability of an Ising-type model, and exact solvability of the 6-vertex, and 8-vertex, models
Pete Rigas
We compute the action-angle coordinates for an Ising type model whose L-operator has been previously studied in the literature by Bazhanov and Sergeev. In comparison to computation…
Intertwining vectors, and Boltzmann weight matrices, of a Solid-on-Solid model from the 20-vertex model
Pete Rigas
We initiate a new study on the correspondence between the 20-vertex model and a SOS (Solid-on-Solid) model. In comparison to two previous works of the author in 2024 which characte…
