Using high-performance computing (HPC) resources at the Jülich Supercomputing Centre, a team of researchers led by Technical University of Dortmund Professor Frithjof Anders is gaining a better understanding of electrons’ behaviors in so-called quantum dots. These nanoscale objects have applications in semiconductor technology and show promise for advancing quantum computing technology, but researchers need to better understand how electrons interact with and influence one another in groups of quantum dots in order to better control them for use in new semiconductors or the qubits inside a quantum computer.

Using JUWELS, the team focused on running simulations that can verify the proposed mechanism for the spin-spin interaction in experimental setups that use magnetic fields and laser pulses to control the electron spin dynamics in the system. The team not only used HPC to simulate in microscopic detail how electrons’ spins influence one another, they were also able to evaluate the use of cross-correlation spectroscopy as a preferred experimental tool for researching these complex, mysterious interactions.
