We show how to create maximally entangled Einstein–Podolsky–Rosen pairs between spatially distant atoms, each of them inside a high-Q optical cavity, by sending pho-tons through a general noisy channel, such as a standard optical fibre. An error-correction scheme that uses few auxiliary atoms in each cavity effectively eliminates photoabsorption and other(More)
Male mosquitoes are attracted by the flight sounds of conspecific females. In males only, the antennal flagellum bears a large number of long hairs and is therefore said to be plumose. As early as 1855, it was proposed that this remarkable antennal anatomy served as a sound-receiving structure. In the present study, the sound-induced vibrations of the(More)
In this article, we build a framework allowing for a systematic investigation of the fundamental issue: " Which quantum states serve as universal resources for measurement-based (one-way) quantum computation? " We start our study by reexamining what is exactly meant by " universality " in quantum computation, and what the implications are for universal(More)
