Long-term Performance Analysis of a Commercial QKD Device Under Real-world Deployment Conditions
Alisson Tezzin, Gustavo M. Uhdre, Oscar Martins +2
Quantum key distribution (QKD) has reached a commercially viable stage, with several companies offering hardware systems designed for operational deployment. Evaluating the perform…
Sufficiency of the counterfactual account of Lüders' rule to rule out ontological models of quantum mechanics
Alisson Tezzin, Bárbara Amaral, Jonte R. Hance
Ontological models, as used in the generalised contextuality literature, play a central role in current research on quantum foundations, providing a framework for defining classica…
Deterministic Underlying States are incompatible with a Counterfactual account of Lüders' rule
Alisson Tezzin, Bárbara Amaral, Jonte R. Hance
In this work, we show that a counterfactual account of L"uders' rule -- which we argue is naturally implied by the mathematical structure of the rule itself -- rules out underlying…
Step-by-step derivation of the algebraic structure of quantum mechanics (or from nondisturbing to quantum correlations by connecting incompatible observables)
Alisson Tezzin
Recently there has been much interest in deriving the quantum formalism and the set of quantum correlations from simple axioms. In this paper, we provide a step-by-step derivation…
Contextuality analysis of disturbing data cannot preserve core Kochen-Specker principles
Alisson Tezzin, Elie Wolfe, Barbara Amaral +1
We address the challenge of extending the criterion for Kochen-Specker contextuality to data with disturbance, to accommodate experimental imperfections or applications to macrosco…
Kochen and Specker's view on functional relations conflicts with the collapse postulate
Alisson Tezzin
A key ingredient of the Kochen-Specker theorem is the so-called functional composition principle, which asserts that hidden states must ascribe values to observables in a way that…
Violating the KCBS inequality with a toy mechanism
Alisson Tezzin
In recent years, much research has been devoted to exploring contextuality in systems that are not strictly quantum, like classical light, and many theory-independent frameworks fo…
Using a resource theoretic perspective to witness and engineer quantum generalized contextuality for prepare-and-measure scenarios
Rafael Wagner, Roberto D. Baldijão, Alisson Tezzin +1
We employ the resource theory of generalized contextuality as a tool for analyzing the structure of prepare-and-measure scenarios. We argue that this framework simplifies proofs of…
Contextuality-by-default for behaviours in compatibility scenarios
Alisson Tezzin, Rafael Wagner, Barbara Amaral
We show that the main idea behind contextuality-by-default (CbD), i.e., the assumption that a physical measurement has to be understood as a contextual collection of random variabl…
