On the relation between completely bounded and -summing maps with applications to quantum XOR games
Marius Junge, Aleksander M. Kubicki, Carlos Palazuelos +1
In this work we show that, given a linear map from a general operator space into the dual of a C-algebra, its completely bounded norm is upper bounded by a universal constant t…
Geometry of Banach spaces: a new route towards Position Based Cryptography
Marius Junge, Aleksander M. Kubicki, Carlos Palazuelos +1
In this work we initiate the study of Position Based Quantum Cryptography (PBQC) from the perspective of geometric functional analysis and its connections with quantum games. The m…
Observers of quantum systems cannot agree to disagree
Patricia Contreras-Tejada, Giannicola Scarpa, Aleksander M. Kubicki +2
Is the world quantum? An active research line in quantum foundations is devoted to exploring what constraints can rule out the postquantum theories that are consistent with experim…
