A ug 2 00 8 Entanglement and Mixed ness of Locally Cloned Non - Maximal W - State

چکیده
In this work we describe a protocol by which two of three parties generate two bipartite entangled state among themselves without involving third party, from a non maximal W state or W type state |X〉 = α|001〉123+β|010〉123+γ|100〉123, α+ β+γ = 1 shared by three distant partners. Also we have considered the case β = γ, to obtain a range for α, for which the local output states are separable and non local output states are inseparable. We also find out the dependence of the mixed ness of inseparable states with their amount of inseparability, for that range of α. PACS numbers: 03.67.-a

As one of the most striking features of quantum phenomena [1], quantum entanglement is playing very important roles in quantum information processing such as quantum computation [2], quantum teleportation [3, 4, 5, 6] (for experimental realization see [7]), dense coding [8] and quantum cryptographic schemes [9, 10, 11]. The separability of pure states for bipartite systems is quite well underst...
متن کاملThe Compositional Structure of Multipartite Quantum Entanglement
While multipartite quantum states constitute a (if not the) key resource for quantum computations and protocols, obtaining a high-level, structural understanding of entanglement involving arbitrarily many qubits is a longstanding open problem in quantum computer science. In this paper we expose the algebraic and graphical structure of the GHZ-state and the W-state, as well as a purely graphical...

Storage and distribution of quantum information are key elements of quantum information processing and quantum communication. Here, using atom-photon entanglement as the main physical resource, we experimentally demonstrate the preparation of a distant atomic quantum memory. Applying a quantum teleportation protocol on a locally prepared state of a photonic qubit, we realized this so-called rem...
