Quantum teleportation of quantum causal structures

Marius Krumm, Philippe Allard Guérin, Thomas Zauner +1

Quantum teleportation is a very helpful information-theoretic protocol that allows to transfer an unknown arbitrary quantum state from one location to another without having to tra…

Noncausal Page-Wootters circuits

Veronika Baumann, Marius Krumm, Philippe Allard Guérin +1

One of the most fundamental open problems in physics is the unification of general relativity and quantum theory to a theory of quantum gravity. An aspect that might become relevan…

A no-go theorem for the persistent reality of Wigner's friend's perception

Philippe Allard Guérin, Veronika Baumann, Flavio Del Santo +1

The notorious Wigner's friend thought experiment (and modifications thereof) has in recent years received renewed interest especially due to new arguments that force us to question…

Probing quantum coherence at a distance and Aharonov-Bohm non-locality

Sebastian Horvat, Philippe Allard Guerin, Luca Apadula +1

In a standard interferometry experiment, one measures the phase difference between two paths by recombining the two wave packets on a beam-splitter. However, it has been recently r…

Quantum computation with indefinite causal structures

Mateus Araújo, Philippe Allard Guérin, Ämin Baumeler

One way to study the physical plausibility of closed timelike curves (CTCs) is to examine their computational power. This has been done for Deutschian CTCs (D-CTCs) and post-select…

Exponential Communication Complexity Advantage from Quantum Superposition of the Direction of Communication

Philippe Allard Guérin, Adrien Feix, Mateus Araújo +1

In communication complexity, a number of distant parties have the task of calculating a distributed function of their inputs, while minimizing the amount of communication between t…

Wigner function negativity and contextuality in quantum computation on rebits

Nicolas Delfosse, Philippe Allard Guerin, Jacob Bian +1

We describe a universal scheme of quantum computation by state injection on rebits (states with real density matrices). For this scheme, we establish contextuality and Wigner funct…
