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:

Qdensity.m

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.

VERSION 3.0-----

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 - Teleportation,
- Quantum fourier transform,
- Grover's search and
- Shor's algorithm,
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 The manual reference is: Bruno Julia Diaz, Joseph M. Burdis and Frank Tabakin, Computer Physics Communications 174 (2006) 914 |

Modifed
26-Aug-2007) NEW: VERSION 2.0 We have updated the package to make it fully compatible with Mathematica 6.0 The QDENSITY package, including: Qdensity.m Cluster.nb Teleportation.nb Grover.nb QFT.nb Shor.nb Tutorial.nb 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 README.txt Courtesy of Jose Luis Gomez The previous version can be obtained here, QDENSITY.1.0.zip |

The package has been tested
using Mathematica
5.0
and 5.2, some functions, using recurrence
formulas, may not work in previous
versions. |
As
provided, print the manual and run the
tutorial, Tutorial.nb, and get
started on how to use QDENSITY to build Quantum Circuits. |

Feedback, corrections,
and commentaries are more than welcome, please email them to tabakin@pitt.edu or bjulia@gmail.com |
Here
are
three snapshots of
a part of the Tutorial
and of Shor and of the
Mathematica QDENSITY palette. |
