Abstract

Quantum entanglement has been known for over sixty years, however the full significance of it as a basic resource in quantum information theory is only being discovered. The fundamental problem is that the decoherence effect due to the environment converts the pure entangled states into a statistical mixture involving some residual noisy entanglement. This leads to an entanglement theory including a scheme of distillation of noisy entanglement within the quantum communication paradigm. This review provides a systematic description of the main (qualitative) results concerning entanglement theory in the context of the so called bound entanglement being a physical manifestation of basic limits for entanglement processing and quantum communication.
