Quantum Stein's lemma revisited, inequalities for quantum entropies, and a concavity theorem of Lieb
نویسندگان
چکیده
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.

From joint convexity of quantum relative entropy to a concavity theorem of Lieb
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.
متن کاملA Minkowski Type Trace Inequality and Strong Subadditivity of Quantum Entropy Ii: Convexity and Concavity
We revisit and prove some convexity inequalities for trace functions conjectured in the earlier part I. The main functional considered is Φp,q(A1, A2, . . . , Am) = (
متن کاملA new inequality for the von Neumann entropy
Strong subadditivity of von Neumann entropy, proved in 1973 by Lieb and Ruskai, is a cornerstone of quantum coding theory. All other known inequalities for entropies of quantum systems may be derived from it. Here we prove a new inequality for the von Neumann entropy which we prove is independent of strong subadditivity: it is an inequality which is true for any four party quantum state, provid...
متن کاملProperties of Nonnegative Hermitian Matrices and New Entropic Inequalities for Noncomposite Quantum Systems
We consider the probability distributions, spin (qudit)-state tomograms and density matrices of quantum states, and their information characteristics, such as Shannon and von Neumann entropies and q-entropies, from the viewpoints of both well-known purely mathematical features of nonnegative numbers and nonnegative matrices and their physical characteristics, such as entanglement and other quan...

We generalize, improve and unify theorems of Rumin, and Maassen– Uffink about classical entropies associated to quantum density matrices. These theorems refer to the classical entropies of the diagonals of a density matrix in two different bases. Thus they provide a kind of uncertainty principle. Our inequalities are sharp because they are exact in the high-temperature or semi-classical limit.
