(Before It's News)

Researchers from the Institut Néel in France and the Karlsruhe Institute of Technology in Germany developed a non-destructive method to continuously read out the state of a single electron spin. The technique is based on the exchange interaction between the spin and a nearby readout quantum dot.

The quantum-dot material is made from a single terbium-two phthalocyanine ligands (Tb-Pc2) molecular magnet embedded in transistor geometry. The QD is cooled down to 40 mK, and at that temperature it can be used to measure electron transport through the ligands, which behave as a readout quantum dot.
