Distinguishing Between Redundancy and Consensus in Quantifying Quantum Objectivity

Explore a comprehensive lecture on quantum objectivity presented by Diana Chisholm from Queen's University Belfast. Delve into rigorous definitions of "redundancy" and "consensus" as distinct measures of quantum state objectivity. Examine how these concepts reflect their everyday meanings and capture different aspects of the quantum-to-classical transition. Discover how spectrum broadcast structure and quantum Darwinism naturally emerge from these measures. Investigate the differences between redundancy and consensus, and their applications in interpreting quantum state objectivity. Learn why using averaged mutual information is crucial in quantum Darwinism to avoid misleading results. Reference recent research papers for in-depth understanding of these concepts and their implications in quantum information and computing.
