Journal ArticleDOI
Quantum discord: a measure of the quantumness of correlations.
TL;DR: This work shows that absence of entanglement does not imply classicality, and considers the vanishing of discord as a criterion for the preferred effectively classical states of a system, i.e., the pointer states.
Journal ArticleDOI
Objective properties from subjective quantum states: Environment as a witness
TL;DR: It is shown that only preferred pointer states of the system can leave a redundant and therefore easily detectable imprint on the environment.
Journal ArticleDOI
Environment as a Witness: Selective Proliferation of Information and Emergence of Objectivity in a Quantum Universe
TL;DR: In this paper, the role of information deposited in the environment of an open quantum system in the course of the decoherence process is investigated as the key to effective objectivity, the essential ingredient of classical reality.
Journal ArticleDOI
Description of a quantum convolutional code.
TL;DR: A quantum error correction scheme aimed at protecting a flow of quantum information over long distance communication is described, largely inspired by the theory of classical convolutional codes which are used in similar circumstances in classical communication.
Journal ArticleDOI
Quantum Serial Turbo Codes
TL;DR: A theory of quantum serial turbo codes, a quantum analogue of a state diagram that provides an efficient way to verify the properties of a quantum convolutional code, and in particular, its recursiveness and the presence of catastrophic error propagation is presented.
