Picturing general quantum subsystems
Octave Mestoudjian, Matt Wilson, Augustin Vanrietvelde +1
We extend the usual process-theoretic view on locality and causality in subsystems (based on the tensor product case) to general quantum systems (i.e.\ possibly non-factor, finite-…
What can we do in a symmetry-constrained perspective? The importance of the total charge's status in quantum reference frame frameworks
Guilhem Doat, Augustin Vanrietvelde
The study of quantum reference frames has received renewed interest over the last years, leading to the parallel development of non-equivalent frameworks by different communities.…
Routing Quantum Control of Causal Order
Maarten Grothus, Alastair A. Abbott, Augustin Vanrietvelde +1
In recent years, various frameworks have been proposed for the study of quantum processes with indefinite causal order. In particular, quantum circuits with quantum control of caus…
Causal Decompositions of 1D Quantum Cellular Automata
Augustin Vanrietvelde, Octave Mestoudjian, Pablo Arrighi
Understanding quantum theory's causal structure stands out as a major matter, since it radically departs from classical notions of causality. We present advances in the research pr…
Unilateral determination of causal order in a cyclic process
Ilyass Mejdoub, Augustin Vanrietvelde
The recent years have seen interest into the possibility for (classical as well as quantum) causal structures that, while remaining logically consistent, feature a cyclic causal or…
Partitions in quantum theory
Augustin Vanrietvelde, Octave Mestoudjian, Pablo Arrighi
Decompositional theories describe the ways in which a global physical system can be split into subsystems, facilitating the study of how different possible partitions of a same sys…
