Multipartite Greenberger-horne-zeilinger Paradoxes for Continuous Variables
We show how to construct Greenberger-Horn-Zeilinger type paradoxes for continuous variable systems. We give two examples corresponding to 3 party and 5 party paradoxes. The paradoxes are revealed by carrying out position and momentum measurements. The structure of the quantum states which lead to these paradoxes is discussed.
متن کاملNMR Greenberger–Horne–Zeilinger states
We describe the creation of a Greenberger–Horne–Zeilinger state of the form (|000〉+ |111〉)/√2 (three maximally entangled quantum bits) using nuclear magnetic resonance. We have successfully carried out the experiment using the proton and carbon spins of trichloroethylene, and confirmed the result using state tomography. We have thus extended the space of entangled quantum states explored system...
متن کاملGreenberger-Horne-Zeilinger paradoxes for many qudits.
We construct Greenberger-Horne-Zeilinger (GHZ) contradictions for three or more parties sharing an entangled state, the dimension of each subsystem being an even integer d. The simplest example that goes beyond the standard GHZ paradox (three qubits) involves five ququats (d=4). We then examine the criteria that a GHZ paradox must satisfy in order to be genuinely M partite and d dimensional.
متن کاملExperimental preparation of quadripartite cluster and Greenberger-Horne-Zeilinger entangled states for continuous variables.
The cluster states and Greenberger-Horne-Zeilinger (GHZ) states are two different types of multipartite quantum entangled states. We present the first experimental results generating continuous variable quadripartite cluster and GHZ entangled states of electromagnetic fields. Utilizing two amplitude-quadrature and two phase-quadrature squeezed states of light and linearly optical transformation...
متن کاملEntanglement distillation from Greenberger-Horne-Zeilinger shares
We study the problem of converting a product of Greenberger-HorneZeilinger (GHZ) states shared by subsets of several parties in an arbitrary way into GHZ states shared by every party. Our result is that if SLOCC transformations are allowed, then the best asymptotic rate is the minimum of bipartite log-ranks of the initial state. This generalizes a result by Strassen on the asymptotic subrank of...
