Entangling operations and their implementation using a small amount of entanglement
arXiv:quant-ph/0007057 · doi:10.1103/PhysRevLett.86.544
Abstract
We study when a physical operation can produce entanglement between two systems initially disentangled. The formalism we develop allows to show that one can perform certain non-local operations with unit probability by performing local measurement on states that are weakly entangled.
