From joint convexity of quantum relative entropy to a concavity theorem of Lieb
نویسنده
چکیده
This paper provides a succinct proof of a 1973 theorem of Lieb that establishes the concavity of a certain trace function. The development relies on a deep result from quantum information theory, the joint convexity of quantum relative entropy, as well as a recent argument due to Carlen and Lieb.

Relative Entropy and the Wigner-Yanase-Dyson-Lieb Concavity in an Interpolation Theory
We show that the Wigner-Yanase-Dyson-Lieb concavity is a general property of an interpolation theory which works between pairs of (hilbertian) seminorms. As an application, the theory extends the relevant work of Lieb and Araki to positive linear forms of arbitrary *-algebras. In this context a "relative entropy" is defined for every pair of positive linear forms of a *-algebra with identity. F...
متن کاملA Minkowski Type Trace Inequality and Strong Subadditivity of Quantum Entropy Ii: Convexity and Concavity

متن کاملQuantum Stein's lemma revisited, inequalities for quantum entropies, and a concavity theorem of Lieb
We give a self-contained, new proof of the monotonicity of the quantum relative entropy which seems to be natural from the point of view of quantum information theory. It is based on the quantum version of Stein’s lemma which provides an operational interpretation of the quantum relative entropy.
متن کاملA Unified Treatment of Convexity of Relative Entropy and Related Trace Functions, with Conditions for Equality
We introduce a generalization of relative entropy derived from the WignerYanase-Dyson entropy and give a simple, self-contained proof that it is convex. Moreover, special cases yield the joint convexity of relative entropy, and for TrK∗ApKB1−p Lieb’s joint concavity in (A,B) for 0 < p < 1 and Ando’s joint convexity for 1 < p ≤ 2. This approach allows us to obtain conditions for equality in thes...
متن کاملSome Operator and Trace Function Convexity Theorems
We consider trace functions (A,B) 7→ Tr[(ABA)] where A and B are positive n × n matrices and ask when these functions are convex or concave. We also consider operator convexity/concavity of ABA and convexity/concavity of the closely related trace functional Tr[ABAC]. The concavity questions are completely resolved, thereby settling cases left open by Hiai; the convexity questions are settled in...
