The theory of entanglement provides a fundamentally new language for describing
interactions and correlations in many-body systems. Its vocabulary consists of qubits and …

A quantum internet is the holy grail of quantum information processing, enabling the
deployment of a broad range of quantum technologies and protocols on a global scale …

Finally, here is a modern, self-contained text on quantum information theory suitable for
graduate-level courses. Develo** the subject'from the ground up'it covers classical results …

The science of quantum information has arisen over the last two decades centered on the
manipulation of individual quanta of information, known as quantum bits or qubits. Quantum …

All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

The entanglement of a pure state of a pair of quantum systems is defined as the entropy of
either member of the pair. The entanglement of formation of a mixed state ρ is the minimum …

Entanglement purification protocols (EPPs) and quantum error-correcting codes (QECCs)
provide two ways of protecting quantum states from interaction with the environment. In an …

We present a measure of entanglement that can be computed effectively for any mixed state
of an arbitrary bipartite system. We show that it does not increase under local manipulations …

We provide necessary and sufficient conditions for separability of mixed states of n-particle
systems. The conditions are formulated in terms of maps which are positive on product …

Quantum information is a rapidly advancing area of interdisciplinary research. It may lead to
real-world applications for communication and computation unavailable without the …
