Quantum computing is the future generation of data processing devices, solving problems faster than classical computers do. One of the approaches is to use the quantum properties of superconductors, often in small dimensions and large magnetic fields. However, there are open questions about how the superconducting properties change at the nanometer scale. Physicists at the Institute for Molecules and Materials (IMM) of Radboud University discovered that for ultrathin aluminum, grown layer by layer on a silicon surface, the temperature at which these layers become superconducting increase as the material gets thinner. This study improves the understanding of two-dimensional superconductivity and may help the development of high-performance quantum computing devices. The results of the study have recently been published in Science Advances.
