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,…
Paradox-free classical non-causality and unambiguous non-locality without entanglement are equivalent
Hippolyte Dourdent, Kyrylo Simonov, Andreas Leitherer +5
Closed timelike curves (CTCs) challenge our conception of causality by allowing information to loop back into its own past. Any consistent description of such scenarios must avoid…
Correlations in a quantum switch-based heat engine with measurements: A proof-of-principle demonstration
Vinicius F. Lisboa, Pedro R. Dieguez, Kyrylo Simonov +1
Allowing the order of quantum operations to exist in superposition is known to open new routes for thermodynamic tasks. We investigate a quantum heat engine where energy exchanges…
Estimation of multivariate traces of states given partial classical information
Kyrylo Simonov, Rafael Wagner, Ernesto Galvão
Bargmann invariants of order , defined as multivariate traces of quantum states , are useful in applications ranging from quantum metrology to cert…
Parallel ergotropy: Maximum work extraction via parallel local unitary operations
Riccardo Castellano, Ranieri Nery, Kyrylo Simonov +1
Maximum quantum work extraction is generally defined in terms of the ergotropy functional, no matter how experimentally complicated is the implementation of the optimal unitary all…
Dimension-independent weak value estimation via controlled SWAP operations
Giulio Chiribella, Kyrylo Simonov, Xuanqiang Zhao
Weak values of quantum observables are a powerful tool for investigating quantum phenomena. Some methods for measuring weak values in the laboratory require weak interactions and p…
Activation of thermal states by coherently controlled thermalization processes
Kyrylo Simonov, Saptarshi Roy, Tamal Guha +2
Thermalization processes degrade the states of any working medium, turning any initial state into a passive state from which no work can be extracted. Recently, it has been shown t…
Query Combinators
Clark C. Evans, Kyrylo Simonov
We introduce Rabbit, a combinator-based query language. Rabbit is designed to let data analysts and other accidental programmers query complex structured data. We combine the funct…
