NEW: Mathematic 9.0-----
Mathematica 9 includes a definition of TensorProduct.
Therefore, to use Qdensity with Mathematica 9.0,
you need to change the package file Qdensity.m by changing
TensorProduct to TensorProductQD everywhere it appears in
the package file Qdensity.m.
A corrected Qdensity.m file can be downloaded at:
NEW: VERSION 4.0-----
There is an addition to the codes "QDENSITY" + "QCWAVE," which
includes quantum systems that are composed of both qubits and qutrits.
These systems include binary (B) qubits and triplet(T) or qutrits,
and hence we call this package BTSystem. You need to access the zip file
which includes a tutorial "BTtutorial.nb," and the package BTSystem.m.
You should place the BTSystem.m file along with the Circuits.m, QCwave.m, and Qdensity.m files
in the directory stipulated in the tutorial.
There is a recent version "QCWAVE,"with many new features available at

|This Mathematica 6.0 package is a
simulation of a Quantum Computer.
The program provides a modular, instructive approach for generating the basic elements that make up a quantum circuit.
The package commands are defined in Qdensity.m which contains the tools needed in quantum circuits, e.g. multiquibit kets, projectors, gates, etc.
A tutorial notebook, Tutorial.nb is provided which should serve as a guide to the package.
Relevant cases, including
Finally, two examples of the construction and manipulation of cluster states, which are part of ``one way computing" ideas, are included as an additional tool in the notebook Cluster.nb. A mathematica palette containing most commands in QDENSITY is also included: QDENSpalette.nb

NEW: VERSION 2.0
We have updated the package to make it fully
compatible with Mathematica 6.0
The QDENSITY package, including:
can be downloaded as a zip file, QDENSITY.2.0.zip. The notebooks can be very conveniently browsed using the Mathematica's Help Browser. The installation is VERY EASY, just follow the short README.txt file

tutorial, Tutorial.nb, and get
started on how to use QDENSITY to build Quantum Circuits.
