=== Rosenfeld et al. (2017): "Event-Ready" Bell test with entangled atoms and closed detection and locality loopholes ===
Physicists at the [[Ludwig Maximilian University of Munich]] and the [[Max Planck Institute of Quantum Optics]] published results from an experiment in which they observed a Bell inequality violation using entangled spin states of two atoms with a separation distance of 398 meters in which the detection loophole, the locality loophole, and the memory loophole were closed. The violation of S = 2.221 ± 0.033 rejected local realism with a significance value of P = 1.02×10<sup>−16</sup> when taking into account 7 months of data and 55000 events or an upper bound of P = 2.57×10<sup>−9</sup> from a single run with 10000 events.<ref>{{cite journal | last1 = Rosenfeld | first1 = W. | last2 = Burchardt | first2 = D. | last3 = Garthoff | first3 = R. | last4 = Redeker | first4 = K. | last5 = Ortegel | first5 = N. | last6 = Rau | first6 = M. | last7 = Weinfurter | first7 = H. | year = 2017 | title = Event-Ready Bell Test Using Entangled Atoms Simultaneously Closing Detection and Locality Loopholes | journal = Physical Review Letters | volume = 119 | issue = 1| page = 010402 | doi = 10.1103/PhysRevLett.119.010402 | pmid = 28731745 | bibcode=2017PhRvL.119a0402R|arxiv = 1611.04604 | s2cid = 10424009 }}</ref>
