Bell States, Dense Coding, and Teleportation
نویسنده
چکیده
The question of the measurements on the Bell states by making use of mode change (from mixed to pure) of one qubit is considered. Such a mode change cannot be taken advantage of for superluminal communication in teleportation, and it may define constraints on the size of the gates.

The problem of the distinguishability of the Bell states is considered. In the entangled Bell states the individual particles are a mixture. The implication of this for " local interpretation " of the dense coding and teleportation protocols is examined.
متن کاملVariable length universal entanglement concentration by local operations and its application to teleportation and dense coding
Using invariance of the n-th tensored state w.r.t. the n-th symmetric group, we propose a ’variable length’ universal entanglement concentration without classical communication. Like variable length data compression, arbitrary unknown states are concentrated into perfect Bell states and not approximate Bell states and the number of Bell states obtained is equal to the optimal rate asymptoticall...
متن کاملThree particle Hyper Entanglement: Teleportation and Quantum Key Distribution
Entanglement acts as an important resource for quantum information and communication. With entanglement between two quantum bits, protocols have been demonstrated for teleporting an unknown qubit [1], denser coding of information [2] and secure communication [3]. An arbitrary qubit can be teleported from one particle to another, irrespective of the distance, with the use of an entangled pair of...
متن کاملTeleportation and dense coding with genuine multipartite entanglement.
We present an explicit protocol E0 for faithfully teleporting an arbitrary two-qubit state via a genuine four-qubit entangled state. By construction, our four-partite state is not reducible to a pair of Bell states. Its properties are compared and contrasted with those of the four-party Greenberger-Horne-Zeilinger and W states. We also give a dense coding scheme D0 involving our state as a shar...
متن کاملTeleportation, Braid Group and Temperley–Lieb Algebra
In the paper, we describe the teleportation from the viewpoints of the braid group and Temperley–Lieb algebra. We propose the virtual braid teleportation which exploits the teleportation swapping and identifies unitary braid representations with universal quantum gates, and further suggest the braid teleportation which is explained in terms of the crossed measurement and the state model of knot...
