A list of tools created by Professor Cahay's research group.

Research and Teaching Tools

Our research group has created the following tools for use in research and education.

Bloch Sphere Simulator

The Bloch sphere concept is a useful tool to represent the actions of various quantum-mechanical operators on a spinor. The Bloch sphere concept is often used in discussions of spin-based quantum computing. The following link described a Bloch Sphere animation software that allows users to view the evolution of the state of a qubit (quantum bit) on the Bloch Sphere when submitted to the action of various quantum gates. The simulator provides documentation on the actions of the simple operators and also provides a description of the time evolution simulation of a qubit submitted to the action of a constant uniform magnetic field. 

You can access the Bloch Sphere simulator from this location.

Secondary Emissions Yield Fitting Program

You can download the GUI which allows a fit to secondary emission yield data as a function of the electron impact voltage based on a new empirical formula described in the attached paper. The new empirical fit is a generalization of a formula first proposed by Vaughan (IEEE Transactions on Electron Devices, Vol.36, 1963 (1989)). Before using the software, read the following paper which describes the theory behind it:
