13.1 Introduction

Quantum entanglement is one of the central notions of quantum information theory (1). One of the basic questions in the entanglement theory is distillability of composite mixed quantum states (2). Roughly speaking a state is distillable if it can be converted into a pure maximally entangled state via local operations and classical communication (LOCC) (2,3). The concept of distillation of “noisy” entanglement has played an important role in quantum communication. In particular, it ...
