Quantum Information: Philosophical, Mathematical
and Experimental Perspectives
The present issue of “Quantum Information Processing” (QIP) as well
as the two subsequent issues will be a forum for a subset of distinguished
speakers and authors who met at the University of Vienna in May 2005
to contribute to the international conference “Quantum Physics of Nature
(QUPON2005)” and the 6th European workshop on “Quantum informa-
tion processing and communication (QIPC)”.
There is always a good reason for a top-level scientiﬁc meeting. But
this time several additional motivations called for an event with outstand-
ing scientists: The year 2005 was not only ofﬁcially declared to be the
UNESCO World Year of Physics, it was also the 100th anniversary of
Albert Einstein’s paper on the quantum nature of light—, which marks the
birthday of quantum optics. It also happened that the ﬁrst day of the con-
ference coincided with Anton Zeilinger’s 60th birthday, which is seen by
many of us as an important date for Quantum Optics and QIP.
While work on the foundations of quantum physics has long been
regarded as a subject for philosophers rather than physicists, it has now
transformed into an information science and correspondingly into an
important ﬁeld of research everywhere in the world: QIP is substantially
and very successfully supported by the European Commission. The Amer-
ican physical society has started a new topical group to create a forum for
QI. And the theme of “quantum information” (QI) has been the seed for a
growing number of new research institutes in the US, Canada or Europe.
Strong scientiﬁc and even already industrial consortia are also working in
Asia and Australia towards quantum computing and quantum communi-
cation. And African groups are by now connected to the QI community,
About 300 participants from 35 different countries and ﬁve conti-
nents attended QUPON2005 and QIPC2005 at the University of Vienna.
