Quantum entropy-typical subspace and universal data compression
Quantum data compression is one of the most fundamental tasks in quantum information theory[1, 2]. Schumacher first provided a tight bound (equal to the von Neumann entropy of the source) to which quantum information may be compressed[3]. From then on, many compression schemes have been proposed[4–13]. In this paper we will consider the universal quantum data compression in the case that we onl...
متن کاملQuantum Dynamical Entropy from Relative entropy
In this exposition we prove an existence theorem for a quantum mechanical dynamical entropy based on von-Neumann’s measurement theory. To that end we introduced a Shannon type of information associated with a quantum channel or measurement based on Araki’s relative entropy. This is an invariance for the dynamics which generalizes Kolmogorov-Sinai ’s notion of dynamical entropy of a measure pres...
متن کاملMonotonicity of quantum relative entropy and recoverability
The relative entropy is a principal measure of distinguishability in quantum information theory, with its most important property being that it is non-increasing under noisy quantum operations. Here, we establish a remainder term for this inequality that quantifies how well one can recover from a loss of information by employing a rotated Petz recovery map. The main approach for proving this re...
متن کاملInequalities for Quantum Relative Entropy
Some logarithmic trace inequalities involving the notions of relative entropy are reobtained from a log-majorization result. The thermodynamic inequality is generalized and a chain of equivalent statements involving this inequality and the Peierls-Bogoliubov inequality is obtained.
متن کاملEfficient optimization of the quantum relative entropy
Many quantum information measures can be written as an optimization of the quantum relative entropy between sets of states. For example, the relative entropy of entanglement of a state is the minimum relative entropy to the set of separable states. The various capacities of quantum channels can also be written in this way. We propose a unified framework to numerically compute these quantities u...
