Constraints on physical computers in holographic spacetimes
Aleksander M. Kubicki, Alex May, David Pérez-Garcia
Within the setting of the AdS/CFT correspondence, we ask about the power of computers in the presence of gravity. We show that there are computations on qubits which cannot be…
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…
Resource Quantification for the No-Programming Theorem
Aleksander M. Kubicki, Carlos Palazuelos, David Pérez-García
The no-programming theorem prohibits the existence of a Universal Programmable Quantum Processor. This statement has several implications in relation to quantum computation, but al…
Localization for Dirac fermions
Aleksander M. Kubicki, Hans Westman, Juan Leon
This work is devoted to incorporating into QFT the notion that particles and hence the particle states should be localizable in space. It focuses on the case of the Dirac field in…
Inelastic Maxwell models for monodisperse gas-solid flows
Aleksander Kubicki, Vicente Garzó
The Boltzmann equation for -dimensional inelastic Maxwell models is considered to analyze transport properties for monodisperse gas-solid suspensions. The influence of the inter…
