Quantum conditional entropy from information-theoretic principles
Sarah Brandsen, Isabelle J. Geng, Mark M. Wilde +1
We introduce an axiomatic approach for characterizing quantum conditional entropy. Our approach relies on two physically motivated axioms: monotonicity under conditional majorizati…
What is Entropy? A new perspective from games of chance
Sarah Brandsen, Isabelle Jianing Geng, Gilad Gour
Given entropy's central role in multiple areas of physics and science, one important task is to develop a systematic and unifying approach to defining entropy. Games of chance beco…
Symmetric distinguishability as a quantum resource
Robert Salzmann, Nilanjana Datta, Gilad Gour +2
We develop a resource theory of symmetric distinguishability, the fundamental objects of which are elementary quantum information sources, i.e., sources that emit one of two possib…
