Summary

Story summary

Researchers at Delft University of Technology observed the real-time flipping of titanium-49 nuclear spin using a scanning tunneling microscope.
The nuclear spin remained stable for five seconds, enabling precise control of nuclear magnetism.
They measured the nuclear state indirectly through hyperfine interactions between electron and nuclear spins.
This method achieved high-fidelity single-shot readout, essential for quantum sensing applications.
Future research will focus on extending lifetimes and investigating arrays of nuclear spins.
