Causal Trade-Offs in Superluminal Extensions of Relativity. A no-go theorem
Amrapali Sen, Matthias Salzger, V. Vilasini
Extensions of relativity that include superluminal reference frames have recently been proposed by Dragan and Ekert as a way to reconcile relativistic symmetry with quantum uncerta…
Higher-order quantum processes respecting closed labs in a spacetime have quantum controlled causal order
Matthias Salzger, V. Vilasini
In quantum causality and quantum information, there is a vast landscape of abstract quantum protocols permitting cyclic or non-acyclic causal structures between operations, includi…
A structure theorem for complex-valued quasiprobability representations of physical theories
Rafael Wagner, Roberto D. Baldijão, Matthias Salzger +3
Quasiprobability representations are well-established tools in quantum information science, with applications ranging from the classical simulability of quantum computation to quan…
Superluminal Quantum Reference Frames
Amrapali Sen, Matthias Salzger, Łukasz Rudnicki
While particles cannot travel faster than the speed of light, nor can information, this assumption has over the years been frequently questioned. Most recently, it has been argued…
A decompositional framework for process theories in spacetime
Matthias Salzger, John H. Selby
There has been a recent surge of interest within the field of quantum foundations regarding incorporating ideas from general relativity and quantum gravity. However, many quantum i…
Mapping indefinite causal order processes to composable quantum protocols in a spacetime
Matthias Salzger, V. Vilasini
Formalisms for higher order quantum processes provide a theoretical formalisation of quantum processes where the order of agents' operations need not be definite and acyclic, but m…
Connecting indefinite causal order processes to composable quantum protocols in a spacetime
Matthias Salzger
Process matrices are a framework to model causal relations in the absence of a well-defined acyclic causal order. The framework is very general and does not even assume the existen…
