What makes a causal loop consistent?
Hippolyte Dourdent, Andreas Leitherer, Emanuel-Cristian Boghiu +3
Causal loops escape paradoxes if they generate valid probabilities under arbitrary independent local interventions. We show that a deterministic classical process is logically cons…
Higher-order quantum thermodynamics: equilibrium and causal structure
Simon Milz, Kyrylo Simonov, Zoltán Zimborás +3
Quantum thermodynamics is traditionally formulated as a theory of equilibrium states and state transformations. Recent advances in higher-order quantum transformations, which descr…
Proof-of-Principle Implementation of Quantum Key Distribution in an Indefinite Causal Order
Yann Valibouse, Martí Cladera-Rosselló, Michael Antesberger +6
In quantum physics, the order in which different operations occur can be placed in superposition. The resulting processes have an indefinite causal order, which is of fundamental i…
Higher-order transformations of bidirectional quantum processes
Luca Apadula, Alessandro Bisio, Giulio Chiribella +2
Bidirectional devices are devices for which the roles of the input and output ports can be exchanged. Mathematically, these devices are described by bistochastic quantum channels,…
