Phys. Rev. Lett. 98, 220403 (2007) [4 pages]Detection Loophole in Asymmetric Bell ExperimentsReceived 13 February 2007; published 31 May 2007 The problem of closing the detection loophole with asymmetric systems, such as entangled atom-photon pairs, is addressed. We show that, for the Bell inequality I3322, a minimal detection efficiency of 43% can be tolerated for one of the particles, if the other one is always detected. We also study the influence of noise and discuss the prospects of experimental implementation. © 2007 The American Physical Society URL:
