Inevitability of knowing less than nothing
Gilad Gour, Mark M. Wilde, Sarah Brandsen +1
A colloquial interpretation of entropy is that it is the knowledge gained upon learning the outcome of a random experiment. Conditional entropy is then interpreted as the knowledge…
Extending Resource Monotones using Kan Extensions
Robin Cockett, Isabelle Jianing Geng, Carlo Maria Scandolo +1
In this paper we generalize the framework proposed by Gour and Tomamichel regarding extensions of monotones for resource theories. A monotone for a resource theory assigns a real n…
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…
What are the minimal conditions required to define a SIC POVM?
Isabelle Jianing Geng, Kimberly Golubeva, Gilad Gour
Symmetric informationally complete (SIC) POVMs are a class of quantum measurements which, in addition to being informationally complete, satisfy three conditions: 1) every POVM ele…
