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…
Impossibility Theorem for Extending Contextuality to Disturbing Systems
Alisson Tezzin, Elie Wolfe, Barbara Amaral +1
Recently there has been much interest and progress in extending the definition of contextuality to systems with disturbance. We prove that such an endeavor cannot simultaneously sa…
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…
