The Quad- Graph: Maximum Contextuality Gap on Eight Vertices
Ugur Tamer, Ãzgür E. MüstecaplıoÄlu, Alper Dizdar +1
Quantum contextuality rules out classical descriptions in which measurement outcomes are independent of the compatible measurements performed alongside them. While the KCBS pentago…
Can the present be the average of the future?
Z. Gedik
We introduce a two state vector formalism of quantum mechanics by generalizing Bell hidden variable model to higher dimensions and by attributing a physical significance, a state e…
Contextuality from the Projector Overlap Matrix
Ali Can Günhan, Semahi Serhat Aksoy, Zafer Gedik
We place several known indicators of Kochen--Specker contextuality -- the KCBS correlator , the contextual fraction $\CF$, the Shannon-entropic -cycle inequality of Chaves a…
Generalized Numerical Construction of MUBs: A Group Theoretical Investigation
BuÄra Gültekin, Solomon B. Samuel, Zafer Gedik
Mutually Unbiased Bases (MUBs) constitute a fundamental geometric structure in quantum theory, known for providing an optimal measurement scheme for quantum state tomography. In pr…
Fidelity-Age-Aware Scheduling in Quantum Repeater Networks
Ozgur Ercetin, Zafer Gedik
Quantum repeater networks distribute entanglement over long distances but must balance fidelity, delay, and resource contention. Prior work optimized throughput and end-to-end fide…
Information-Theoretic and Operational Measures of Quantum Contextuality
Ali Can Günhan, Zafer Gedik
We propose an information -- theoretic framework for quantifying Kochen-Specker contextuality. Two complementary measures are introduced: the mutual information energy, a state-ind…
