Contextuality in Composite Systems: The Role of Entanglement in the Kochen-Specker Theorem

Explore the interplay between contextuality and entanglement in composite quantum systems through this comprehensive lecture. Delve into the radical departure of quantum theory from classical thinking, examining how entanglement and Bell's theorem demonstrate nonclassicality in multi-party scenarios. Investigate the Kochen-Specker theorem and its implications for contextuality in single systems. Analyze recent findings on the relationship between contextuality and entanglement in composite systems, and consider their impact on restricted models of multiqubit quantum computation with state injection. Based on research by V.J. Wright and R. Kunjwal, published in Quantum 7, 900 (2023), this talk provides valuable insights into quantum information and quantum computing concepts.
