science ⚛️ Mapping 7 electrons in quantum dots
Researchers successfully mapped the energy spectra of up to seven electrons inside gallium arsenide quantum dots. The team from University of Sheffield, Johannes Kepler University Linz, and University of Sussex achieved this using nuclear spins as a non-invasive probe. Experiments were conducted on low-strain GaAs/AlGaAs epitaxial dots, showing findings from dates around the study. This work opens up few-electron states as a new operating regime for optically active quantum dots. This is a huge step toward building more practical and robust quantum computing systems. ⚛️
