Self-testing tilted strategies for maximal loophole-free nonlocality
Nicolas Gigena, Ekta Panwar, Giovanni Scala +3
The degree of experimentally attainable nonlocality, as gauged by the loophole-free or effective violation of Bell inequalities, remains severely limited due to inefficient detecto…
Probability in two deterministic universes
Mateus Araújo
How can probabilities make sense in a deterministic many-worlds theory? We address two facets of this problem: why should rational agents assign subjective probabilities to branchi…
Experimental entanglement of temporal order
Giulia Rubino, Lee A. Rozema, Francesco Massa +4
The study of causal relations has recently been applied to the quantum realm, leading to the discovery that not all physical processes have a definite causal structure. While indef…
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…
Experimental Verification of an Indefinite Causal Order
Giulia Rubino, Lee A. Rozema, Adrien Feix +5
Investigating the role of causal order in quantum mechanics has recently revealed that the causal distribution of events may not be a-priori well-defined in quantum theory. While t…
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…
Characterizing finite-dimensional quantum behavior
Miguel Navascues, Adrien Feix, Mateus Araujo +1
We study and extend the semidefinite programming (SDP) hierarchies introduced in [Phys. Rev. Lett. 115, 020501] for the characterization of the statistical correlations arising fro…
Experimental Superposition of Orders of Quantum Gates
Lorenzo M. Procopio, Amir Moqanaki, Mateus Araújo +7
In a quantum computer, creating superpositions of quantum bits (qubits) in different states can lead to a speed-up over classical computers [1], but quantum mechanics also allows f…
Computational advantage from quantum-controlled ordering of gates
Mateus Araújo, Fabio Costa, Časlav Brukner
It is usually assumed that a quantum computation is performed by applying gates in a specific order. One can relax this assumption by allowing a control quantum system to switch th…
Experimental Test of the Quantum Violation of the Noncontextuality Inequalities for the n-Cycle Scenario
Gilberto Borges, Marcos Carvalho, Pierre-Louis de Assis +5
The inequalities that separate contextual from noncontextual correlations for the n-cycle scenario (consisting of n dichotomic observables Oj, with j = 0, ..., n-1 and such that Oj…
Quantum realism and quantum surrealism
Mateus Araújo
In this thesis we explore the questions of what should be considered a "classical" theory, and which aspects of quantum theory cannot be captured by any theory that respects our in…
