Quantum Optics Maple Toolbox

These are modules and worksheets for the Quantavo Toolbox, designed to ease certain calculations in Quantum Optics and Quantum Information. For more details visit


  1. If you download the file " Quantavo.mpl" and save it as


Then open a Maple worksheet and execute,

read "/my-directory/Quantavo.mpl"; with(Quantavo);

That should display all the available procedures. That's it!

  1. If you download the file "", then Uncompress its content to a given directory,


open a Maple worksheet and execute,

read "/my-directory/QUANTAVO/Quantavo.mpl"; with(Quantavo);

You may also execute the file "" to find some examples.

(for windows use double slash, > read "C:\my-directory\QUANTAVO\Quantavo.mpl";)


Declare States in the Fock basis and let them evolve with an arbitrary unitary transformation of the modes: Example 1

Plot and display density matrices and pure quantum states: Example 2

Evaluate and plot the Negativity (Entanglement Measure) for different states: Example 2
