<\body> is a high level, architecture independent programming language for quantum computers, with a syntax derived from classical procedural languages like C or Pascal. This allows for the complete implementation and simulation of quantum algorithms (including classical components) in one consistent formalism. QCL is developed by |http://tph.tuwien.ac.at/~oemer/qcl.html>. The interface is mainly useful for displaying quantum states in a readable way. <\initial> <\collection> <\references> <\collection> > > > > > > > > > > > > > > > > > >
