Briefings

Delft University of Technology researchers successfully controlled the nuclear spin of a single atom using radio-frequency signals, a breakthrough that challenges previous assumptions about nuclear spin manipulation. The team used a refined double magnetic resonance technique to independently address electron and nuclear spins, flipping the nuclear spin even when the two were largely disentangled. This discovery was published in Nature Communications and could inform methods for storing and reading quantum information, though the underlying mechanism remains unresolved.

Key points

• Researchers at Delft University of Technology controlled the nuclear spin of a single atom using radio-frequency signals, challenging the belief that nuclear spin could not be manipulated directly.
• The team used a refined double magnetic resonance technique to independently address electron and nuclear spins, successfully flipping the nuclear spin even when the two were largely disentangled.

Context

This finding comes from a press release by Delft University of Technology in The Netherlands, published in Nature Communications. It matters because controlling nuclear spins could open new possibilities for storing and reading quantum information, though the research primarily raises new questions about the mechanism driving the nuclear spin.

Limitations

The evidence is limited to a single press release from Delft University of Technology in The Netherlands. The mechanism driving the nuclear spin response remains unresolved, and the study was conducted using a converted scanning tunnelling microscope to study spins in metals like iron and nickel.
