Titel: Quantum Information in Space-time
Abstract: P. Hayden and A. May introduced the quantum game about summoning quantum information [1] and sufficient and necessary conditions to win it. In this thesis we relax these conditions allowing the output state to be different than the original state.
We found a connection of this problem to optimal cloning machines [3], [7] and we use this connection to find the optimal fidelity we can achieve when we consider the worst case fidelity over the outputs and bounds when we consider the average case fidelity.
