Perfect Teleportation and Superdense Coding with W-states
نویسنده
چکیده
True tripartite entanglement of the state of a system of three qubits can be classified on the basis of stochastic local operations and classical communications (SLOCC). Such states can be classified in two categories: GHZ states and W-states. It is known that GHZ states can be used for teleportation and superdense coding, but the prototype W-state cannot be. However, we show that there is a class of W-states that can be used for perfect teleportation and superdense coding. PACS NO: 03.67.-a, 03.65.Bz Emails : [email protected], [email protected]

As we know, the states of triqubit systems have two important classes: GHZ-class and W-class. In this paper, the states of W-class are considered for teleportation and superdense coding, and are generalized to multi-particle systems. First we describe two transformations of the shared resources for teleportation and superdense coding, which allow many new protocols from some known ones for that...
متن کاملW-states and Quantum Communication Protocols
We consider W-states and generalized W-states for n-qubit systems. We obtain conditions to use these states as quantum resources to teleport unknown states. Only a limited class of multiqubit states can be teleported. For one-qubit states, we use protocols which are simple extensions of the conventional teleportation protocol. We also show that these resource states can be used to transmit at m...
متن کاملA study of the efficiency of the class of W -states as a quantum channel
Recently, a new class of W -states has been defined by Agarwal and Pati [23] and it has been shown that they can be used as a quantum channel for teleportation and superdense coding. In this work, we identify those three-qubit states from the set of the new class of W -states which are most efficient or suitable for quantum teleportation. We show that with some probability |W1〉 = 12 (|100〉+ |01...
متن کاملEntanglement purification with two-way classical communication
Quantum information theory and quantum computation study the use of quantum physics in information processing and computation[1]. Many important results such as quantum teleportation, superdense coding, factoring and search algorithms make use of quantum entanglements as fundamental resources [2, 3, 4, 5]. Therefore, entanglement purification protocols, the procedures by which we extract pure-s...
متن کاملEntanglement Manipulation
Entanglement serves as a resource which we can use to perform novel information processing tasks, in particular communication tasks. For example, superdense coding and teleportation are two such tasks which are impossible classically; they make essential use of entanglement. In this lecture I’m going to cover dense coding and teleportation and then show how we can manipulate entanglement into a...
