  From its inception at the beginning of the eighties, with milestone results
and ideas such as quantum simulation, the no-cloning theorem, and quantum
computers, quantum information has established itself over the next decades,
being nowadays a fast-developing field at the interface between fundamental
science and a variety of promising technologies. In this work we aim to offer a
portrait of this dynamic field, analyzing the statistical properties of the
network of collaborations among its researchers. Using the quant-ph section
from the arXiv as our database, we draw several conclusions on its properties.
In particular, we show that the quantum information network of collaborations
displays the small-world property, is very aggregated and assortative, being
also in line with Newman's findings as for the presence of hubs and the Lotka's
law regarding the average number of publications per author.
