Felipe,

That is the Mapnik stylesheet that OSM uses on the main slippymap  
page, opened in QGIS through the Quantumnik plugin. Quantumnik does  
allow you to author styles from scratch through the QGIS graphical  
interface, but also allows you to open existing styles (READ ONLY).  
So, that style is not authored by QGIS, but rather by hand by the  
brilliance and hard work of many OpenStreetMap contributors.

Again, all Quantumnik is doing is allowing you to browse the maps  
rendered by that style inside QGIS and that requires you also have OSM  
data inside of PostGIS running locally.

For more details see:

http://svn.openstreetmap.org/applications/rendering/mapnik/README

Overall the steps would be:

1) Install postgres/postgis/mapnik
2) install osm2pgsql
3) download osm data
4) import into postgis using osm2pgsql
5) edit the 'osm.xml' style to fit your database configuration
6) test rendering the osm.xml with 'generate_image.py' or 'nik2img,py'

if it works then you have a Mapnik/OSM rendering setup running locally  
and you can open that style in QGIS.
