An operator description of entanglement matching in quantum teleportation
Z. Kurucz, Mátyás Koniorczyk, Петер Адам, József Janszky · Journal of Optics B Quantum and Semiclassical Optics · 2003
The antilinear operator representation of bipartite pure states of the relative state formulation of quantum mechanics is applied to describe quantum teleportation schemes utilizing an arbitrary pure state as the entangled resource. Bennett type teleportation schemes with nonmaximally entangled pure states are characterized and the notion of 'entanglement matching' is introduced in general. Examples, including a scheme based on coherent-state superposition states of the electromagnetic field, are provided.
