  In this short paper we present the main features of a new quantum programming
language proposed recently by Peter Selinger which gives a good idea about the
difficulties of constructing a scalable quantum computer. We show how some of
these difficulties are related to the contextuality of quantum observables and
to the abstract and statistical character of quantun theory (QT). We discuss
also, in some detail, the statistical interpretation (SI) of QT and the
contextuality of observables indicating the importance of these concepts for
the whole domain of quantum information.
