QLunch: Summoning Quantum Information

Speaker: Ignacio Amores Sesar, University of Copenhagen

Title: Summoning Quantum Information

Abstract: We will present the paper "Summoning Information in Spacetime, or Where and When Can a Qubit Be?" by P. Hayden and A. May about under which conditions can we localize a qubit in some regions of spacetime.  Then we will consequences of that result, finding a connexion between this problem and optimal asymmetric cloning machines.
