A numerical perspective on Nature authors.

Quantum computation is very much a team effort at the Institute for Quantum Optics and Quantum Information (IQOQI) and the University of Innsbruck in Austria. Everyone in the Austrian group shares responsibility at each stage — from setting up experiments to analysing results, says the institute's Hartmut Häffner.

Häffner's group also tries to involve other researchers. He says that discussions at conferences often lead to new ideas or experiments. And with the creation of the IQOQI two years ago, which brought together groups of experimental and theoretical physicists, stronger collaborations have grown within Innsbruck itself, Häffner adds. The fruits of one such partnership, looking at entangled quantum particles, are presented on page 643.

14 authors working in Innsbruck report on entangled quantum particles in this week's Nature.

13 papers with contributing authors working in Austria have been published in Nature in 2005 (793 papers have been published in total).

9% is the acceptance rate for papers submitted to Nature from Austria in the course of 2005.

11 Austrian institutes host authors of research published in Nature during 2005.
