We investigate the problem of closing the detection loophole in multipartiteBell tests, and show that the required detection efficiencies can besignificantly lowered compared to the bipartite case. In particular, we presentBell tests based on n-qubit Greenberger-Horne-Zeilinger states, which cantolerate efficiencies as low as 38% for a reasonable number of parties andmeasurements. Even in the presence of a significant amount of noise,efficiencies below 50% can be tolerated, which is encouraging given recentexperimental progress. Finally we give strong evidence that, for a sufficientlylarge number of parties and measurements, arbitrarily small efficiencies can betolerated, even in the presence of an arbitrary large amount of noise.
