ScholarBank@NUS Repository. https://doi.org/10.1103/PhysRevA.70.042106 | Abstract: | The multiparticle generalized Greenberger-Horne-Zeilinger (GHZ) states are discussed. It is found that for a specific range of parameters and for an odd number of qubits they do not violate any Bell inequality for correlation functions. The results show that multiparticle Clauser-Horne-type (CH) inequalities involving probabilities are stronger tools for analyzing violations of local realism in multiparticle systems as compared to inequalities involving correlation functions. The Pitovsky-Svozil CH-type inequalities form a more stringent constraint on local realism as compared to WWWZB correlation-function. | Source Title: | Physical Review A - Atomic, Molecular, and Optical Physics | URI: | http://scholarbank.nus.edu.sg/handle/10635/95825 | ISSN: | 10502947 | DOI: | 10.1103/PhysRevA.70.042106 |
