Quantum information theory of entanglement and measurement ?

We present a quantum information theory that allows for a consistent description of entanglement. It parallels classical (Shannon) information theory but is based entirely on density matrices (rather than probability distributions) for the description of quantum ensembles. We find that quantum conditional entropies can be negative for entangled systems, which leads to a violation of well-known ...

Quantum Entropic Logic Theory . Nonlinear Information Channels and Quantum Entanglement

Quantum entropic logic theory studies general laws of acquisition and processing of information in systems following laws of quantum mechanics, using mathematical models of information transducers – information channels – for researching of such systems’ potentialities, and develops principles of their rational use. Concept of channel capacity is the central one in classic theory of information...

Entanglement Dynamics in Quantum Information Theory

This thesis contributes to the theory of entanglement dynamics, that is, the behaviour of entanglement in systems that are evolving with time. Progressively more complex multipartite systems are considered, starting with low-dimensional tripartite systems, whose entanglement dynamics can nonetheless display surprising properties, progressing through larger networks of interacting particles, and...

Dissipative Quantum Theory: Implications for Quantum Entanglement

Three inter-related topics are discussed here. One, the Lindblad dynamics of quantum dissipative systems; two, quantum entanglement in composite systems and its quantification based on the Tsallis entropy; and three, robustness of entanglement under dissipation. After a brief review of the Lindblad theory of quantum dissipative systems and the idea of quantum entanglement in composite quantum s...
