Demonstration of TCAD simulations of exchange coupling in silicon double quantum dots

Nanoacademic has recently released a commercial computer-aided design software package called QTCAD for quantum hardware based on spin qubits in semiconductors, one of the leading candidates for the implementation of a quantum computer. While several demonstrations of the tool in realistic operation conditions have already been completed with academic and industrial partners, these demonstrations were limited to the case of a single qubit. In this project, the intern will generalize these demonstrations to the two-qubit case by calculating the exchange interaction in a double quantum dot. The exchange interaction determines the speed at which two-qubit quantum logic gates can be implemented in spin qubits. By completing this demonstration and writing a corresponding tutorial, the partner organization will be able to provide its customers from academic, government, and industrial research labs with an additional simulation feature which is required for the design of large-scale quantum computers.
