Explicit circuits for quantum communication through multipartite cluster states

چکیده
Quantum circuits are provided for realizing quantum communicational protocols involving teleportation and quantum information splitting (QIS) of single and two qubit states. We explicate these protocols through cluster states as the same is experimentally achievable. We describe quantum circuits for realizing the four and five partite cluster states using well known gates in quantum information and use them for implementing teleportation of an arbitrary two qubit state and QIS of a single qubit state using the four partite cluster state and the QSS of an arbitrary two qubit state using the five partite cluster state. All the schemes are experimentally realizable as they donot involve entangled measurements. PACS : 03.65.Ud; 03.67.-a; 03.67.Hk; 03.67.Dd

Structure of Multipartite Entanglement in Random Cluster-Like Photonic Systems
Quantum networks are natural scenarios for the communication of information among distributed parties, and the arena of promising schemes for distributed quantum computation. Measurement-based quantum computing is a prominent example of how quantum networking, embodied by the generation of a special class of multipartite states called cluster states, can be used to achieve a powerful paradigm f...

We present a continuous-variable CV Gaussian analog of cluster states, a new class of CV multipartite entangled states that can be generated from squeezing and quantum nondemolition coupling HI= XAXB. The entanglement properties of these states are studied in terms of classical communication and local operations. The graph states as general forms of the cluster states are presented. A chain for...
متن کاملA diagrammatic axiomatisation of the GHZ and W quantum states
In the context of categorical quantum mechanics, Coecke and Kissinger suggested that two 3-qubit states, GHZ and W, may be used as the building blocks of a new graphical calculus, aimed at a diagrammatic classification of multipartite qubit entanglement under stochastic local operations and classical communication (SLOCC). We present a full graphical axiomatisation of the relations between GHZ ...

We investigate continuous-variable (CV) multipartite unlockable bound entangled states. Comparing with the qubit multipartite unlockable bound entangled states, CV multipartite unlockable bound entangled states present some new and different properties.

متن کاملApproximate and Multipartite Quantum Correlation (Communication) Complexity
The concepts of quantum correlation and communication complexity have been proposed to quantify the worst-case computational resources needed in generating bipartite classical distributions or bipartite quantum states in the single-shot setting by Zhang (Proc. 3rd Innov Theor Comput., pp. 39-59, 2012). The former characterizes the minimal size of the initial shared state needed if no communicat...
