Quan is designed to model physical quantities in C++ programs. Advantages include automated dimensional analysis checking, automatic unit conversions, self documentation of code.

Quantities provides an interface to the use of numbers which are associated with a dimension and a unit (physical quantities) in computer calculations (quantity calculus) just like C++ built-in types.

QCS is a quantum computer simulation written by Philipp Jungmann, Torsten Mandel and Maximilian Plenert as a software project under Dr. Michael Winckler (IWR) and Dr. Jian-Wei Pan (PI), University of Heidelberg.

Calculate electronic properties of graphene-like systems with a user friendly interface. The code uses the tight binding approximation and it is able to stude in a 0D, 1D and 2D geometries, orbital and magnetic fields, intrinsic and extrinsic spin-orbit coupling, sublattice imbalance, and interactions at the mean field level.

Quantum Information Toolkit is a comprehensive, easy-to-use interactive numerical toolkit for quantum information and computing, available for both MATLAB and Python.

qsims simulates quantum dynamics with an (almost) arbitrary time-dependent Hamiltonian. qsims uses a Chebychev polynomial expansion of the Schrodinger propagator, and the pseudospectral method developed by R. Kosloff.

The Quantum Systems Simulator gives you time-dependent quantum computations (and other QM systems); an easy, intuitive interface for building complex Hamiltonians out of simple ones; and SPEED: 2-3x faster than Matlab on tested problems.

Quantum Mechanical Toolkit And 3D Viewer for C++. Allows Data Visualisation via Images, Surfaces and Volume plots using OpenGL, as well as rapid development Quantum Mechanical Simulations. Uses the Blitz++, VTK Visualisation and Qt Libraries.

Quantum walk library is set of tools for simulations of quantum walks (for chiral or achiral particles) on graphs based on Zarja library.

QuantimSim is a physics simulation engine. Some aspects of astrophysics, electromagnetism, relativity, thermodynamics, statistical mechanics and quantum mechanics will be included in the simulation library.

A simple little program, that can convert quaternions from a exponential form to a usual form. I will argue for this method, which I find very natural and quite intuitive.

Unified Environment Handler that sits on OpenGLUT's head, processing collisions, friction, etc, as well as including extended lighting, shading, and anti-aliasing not native to OpenGLUT.

QuickFlash is a C++-based analysis library for data files generated by the Flash hydrodynamics code. It provides high-performance access to large datasets in low memory situations and other restrictive environments.

Data evaluation tool for the magnetism reflectometer at the spallation neutron source (BL-4A@SNS). Reads raw nexus files (HDF5) of histogrammed or event mode data to create reflectivity curves and 2D Q-maps.

Graphical user interface for gnuplot to create publication quality figure very quickly. It supports templates for fast formatting of graphics, different plot styles, insets, axis and label options. One important feature is storing metadata in png and pdf files that can be used to reload any graph saved with QuickPlot.

Interactive program to perform quantum transport calculations by means of the Landauer and scattering matrix formalism, in a two terminal geometry. The Hamiltonians of leads and scattering region can be modified, adding exchange fields, mass, spin-orbit coupling or superconductivity.

We use R (www.r-project.org) in order to generate a greater specificity and sensitivity of protein identification by Mass Spectrometry. These functions are implemented as add-on packages to the open source GPL software R.

Robotic Manipulator Development and Simulation Environment in Python and Blender. IMPORTANT: Development moved to github. http://github.com/ajnsit/r2d3

RAtom solves nonlinear Kohn-Sham equation for the neutral atom. The adaptive algorithm based on finite element method (FEM) is implemented. Discretization of the differential eigenvalue problem is done by finite element method with Lobatto polynomials as a basis functions. High order Gauss quadratures are applied in order to obtain the total energy of atom with absolut accuracy of 1E-6 hartree. Disctretization leads to generalized eigenvalue problem, which is solved by procedures from LAPACK libraries. The program is implemented in C++, it runs as a single thread. The implemented algorithm is described in the following papers: 1. Z. Romanowski, "Adaptive solver of a Kohn-Sham equation for an atom", Modelling Simul. Mater. Sci. Eng. vol. 17, 045001 (2009) 2. Z. Romanowski, "Application of h-adaptive, high order finite element method to solve radial Schrödinger equation", Molecular Physics, vol. 107, pp. 1339-1348 (2009). Further questions: romz@wp.pl
