Detection loophole in asymmetric Bell experiments
arXiv:quant-ph/0702130 · doi:10.1103/PhysRevLett.98.220403
Abstract
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 I_3322, 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.
