http://www.maplesoft.com/applications/view.aspx?SID=4812&ref=Feed
PX is a Maple package designed to implement non-commutative multiplication and commutation of quantum operators. In particular it is designed to deal with systems with several degree of freedom satisfying the commutation relations of operators and their conjugate momenta; i.e., operators such as p[x] and x, or alternatively their associated annihilation and creation operators.<img src="/view.aspx?si=4812//applications/images/app_image_blank_lg.jpg" alt="PX: A package for multiplication and commutation of quantum operators" align="left"/>PX is a Maple package designed to implement non-commutative multiplication and commutation of quantum operators.

The Grover algorithm is a realization of quantum advantages, which we can use in the "search task". This is quantum algorithm for quantum computer, and it is difficulty to realize such algorithm with the ordinary machine. However, also with a power of the personal computer we can give some common image of the algorithm.<img src="/view.aspx?si=1448/Grover_64.gif" alt="Quantum Grover`s algorithm" align="left"/>The Grover algorithm is a realization of quantum advantages, which we can use in the "search task".

http://www.maplesoft.com/applications/view.aspx?SID=4260&ref=Feed
The new ScientificConstants package in Maple 8 provides the values, symbols, uncertainty and units of over 13,000 physical constants. Never again do you have to search the internet or grab a reference book to look up such values. This extensive package gives you access to the basic chemical properties of any element or isotope from the Periodic Table. Also available are 70 physical constants, such as Planck's constant, the Newtonian constant of gravitation, magnetic flux quantum, and speed of light in a vacuum. If a specific physical constant that you need is not included, simply add the constants you commonly use to Maple's database. This flexible package also allows you to modify properties or change the system associated with a constant. The ScientificConstants package in conjunction with the comprehensive Units package introduced in Maple 7 together provide valuable tools for scientists and engineers.<img src="/view.aspx?si=4260//applications/images/app_image_blank_lg.jpg" alt="The ScientificConstants Package" align="left"/>The new ScientificConstants package in Maple 8 provides the values, symbols, uncertainty and units of over 13,000 physical constants.

Solution of the Schroedinger equation by the Numerov-method for any given one-dimensional eigenvalue problem is shown here. The central idea is to fix the eigenvalue and solve the differential equation. If the resulting function is not an eigenfunction, the deviation serves as a guide how to change the eigenvalue. Here follows an abstract of the theory.<img src="/view.aspx?si=3828//applications/images/app_image_blank_lg.jpg" alt="Solution of the 1-D Schroedinger equation" align="left"/>Solution of the Schroedinger equation by the Numerov-method for any given one-dimensional eigenvalue problem is shown here.
