Short Description
We want to use the Finite Element Method (FEM) for numerical simulations of transistors to be used for quantum computing. The existing C++ code at IIS that solves this quantum transport problem is based on finite differences. However, compared to finite differences, FEM employs unstructured meshes that allow for more complicated geometries and local refinement. The project aims at supporting the development the current code and running the numerical simulations.
The Big Picture
The idea of quantum computing is to associate a bit to a two-state quantum phenomenon (a “qu-bit”), so that any linear combination between the two states is allowed and more information can be conveyed than a classical bit. The SPIN project is a new collaboration between Swiss institutions to build silicon-based transistors that can act as quantum devices, so to rely on existing hardware for quantum computers. Specifically, at IIS we plan to simulate these transistors numerically: the best models are then going to be manufactured by IBM Research.

Throughout the history of this department, scientists have made major contributions to the advancement of knowledge in solid-state physics, stimulated by problems relevant to technology. Today research focuses on different areas of technological significance, such as photonics and optoelectronics, CMOS and post-CMOS, micro fabrication, packaging and life sciences. This effort is supported by the newly opened Binnig and Rohrer Nanotechnology Centre, offering state of the art micro fabrication yet with the required flexibility for any research at the frontier between industrial and academic research.
With more than 100 students and young researchers (including Master and PhD students, as well as postdoctoral researchers), our laboratory offers a dynamic and international environment for excellent science and provides a unique opportunity to extend your research skills. The laboratory equipment for the project defined in this Master thesis is state-of-the art, and allows to perform novel and exciting experiments.

Prerequisites
We are seeking a candidate with an interest in numerical methods for engineering simulations and some background in C++ programming. Basic knowledge of semiconductor quantum transport formalism (NEGF) will be helpful, but is not required. Similarly, knowledge of C++ parallelization libraries such as MPI and CUDA, as well as a basic grasp on High Performance Computing, is advantageous, but also not necessary.
