The quantum computation package 
for Mathematica®  4.0
 

Introduction
QuCalc is a library of Mathematica functions whose purpose is to simulate quantum circuits and solve problems of quantum computation. The package has been developed by Paul Dumais of the Laboratory for Theoretical and Quantum Computing of Université de Montreal (also a member of the Crypto and Quantum Info Lab at McGill University).

Features of QuCalc include:

• Built-in definition of qubits, qutrits, density matrices;
• Implementation of tensorial product, tensorial division;
• Definition of the trace-out operation, ancillary systems;
• Enables all sorts of operations: measures, superoperators, POVMs, etc.;
• Numerical calculation of fidelity of mixed states, and von Neumann entropy.


Files to download

• QuCalc (Mathematica package)
• Documentation (english) (by Paul Dumais and Hugo Touchette)

Installation
• Download the file "QuCalc.m" on your personal computer or in your Unix account, in the directory ".../Kernel". To know exactly where that directory is, type $Path in Mathematica.
• Start Mathematica and load the QuCalc package by typing "<<QuCalc`".
