Core Insights - The research team from Delft University of Technology has successfully observed the flipping of nuclear spin states in real-time, marking a significant advancement in atomic-scale quantum detection [1][5][7] - The study utilized a scanning tunneling microscope (STM) to indirectly measure the nuclear spin state by detecting changes in the electronic states of individual atoms [1][5][7] Group 1: Research Methodology - The team selected titanium atoms with nuclear spin characteristics on a strontium titanate substrate as the observation target [5] - The STM tip captures signals corresponding to the conversion of nuclear spin between two quantum states by sensing the electronic states surrounding the atom [5][7] Group 2: Key Findings - The nuclear spin state was found to average around 5 seconds, while the electronic spin of the same atom had a lifespan of only 100 nanoseconds [7] - This achievement represents the first single-shot readout of nuclear spin at the atomic scale, overcoming the technical limitations of STM in directly detecting nuclear spins [7] Group 3: Publication and Impact - The research findings were published on August 21 in the journal Nature Communications [7]
