This Letter presents a nonclassical mechanism of two-atom interferometry. The interferometer introduces two different yet indistinguishable alternatives for randomly paired atoms to create joint atom-detection event. superposition amplitudes yields interference with peculiar features which outshine the classic atom interferometer: (1) is still observable when time delay greater than coherence b...

PURPOSE To assess the accuracy of a newly described macular function test (Vryghem macular function test) adapted to our examination equipment and to compare it to the Lotmar-light interferometer for the preoperative evaluation of cataract patients at the University Eye Clinic, Geneva, Switzerland. METHODS This prospective study included 71 consecutive patients (72 eyes) who were undergoing u...
