Abstract We propose the information-theoretic quantity of geometric quantum discord (GQD) as an indicator of the factorization properties of a given quantum system. In particular. we show how non-vanishing discord implies that the corresponding partition function does not factorize. both for generic pure states and the thermofield double state as a state with a known geometric dual in... https://www.trangtinamthuc.com/product-category/pasta-rice-noodles/
