Title: | A witness of multipartite entanglement strata | Authors: | Kaszlikowski, D. Kay, A. |
Issue Date: | 20-May-2008 | Citation: | Kaszlikowski, D., Kay, A. (2008-05-20). A witness of multipartite entanglement strata. New Journal of Physics 10 : -. ScholarBank@NUS Repository. https://doi.org/10.1088/1367-2630/10/5/053026 | Abstract: | We describe an entanglement witness for N-qubit mixed states based on the properties of N-point correlation functions. As the degree of violation increases beyond different threshold values, or strata, this witness can guarantee that no more than M qubits are separable from the rest of the state for any M ≤ N, or that there is some genuine M-party or greater multipartite entanglement present. We illustrate the use our criterion by investigating the existence of entanglement in thermal stabilizer states, where we demonstrate that the witness is capable of witnessing bound-entangled states. Intriguingly, this entanglement can be shown to persist in the thermodynamic limit at arbitrary temperature. © IOP Publishing Ltd and Deutsche Physikalische Gesellschaft. | Source Title: | New Journal of Physics | URI: | http://scholarbank.nus.edu.sg/handle/10635/95704 | ISSN: | 13672630 | DOI: | 10.1088/1367-2630/10/5/053026 |
