Abstract |
A large number of tasks in Quantum Information can be viewed as "state transformation games", where the goal of the players is to transform a given input state in some desired way. This is the case of quantum state discrimination, quantum cloning, amplification, conjugation, and purification. The first part of this talk will present some general results about state transformation games, including the maximum payoff achievable with or without entanglement, using deterministic or probabilistic strategies. The second part of the talk will focus on the example of games in the asymptotic scenario, discussing the new phenomena of quantum replication and fidelity activation. |
