Electron spin control: Levitated nanodiamond is research gem

I’m telling folks there is much to be learn in the usage of natural and synthetic resources especially around diamonds — Nanodiamonds Magic.

WEST LAFAYETTE, Ind. — Researchers have demonstrated how to control the “electron spin” of a nanodiamond while it is levitated with lasers in a vacuum, an advance that could find applications in quantum information processing, sensors and studies into the fundamental physics of quantum mechanics.

Electrons can be thought of as having two distinct spin states, “up” or “down.” The researchers were able to detect and control the electron spin resonance, or its change from one state to the other.

“We’ve shown how to continuously flip the electron spin in a nanodiamond levitated in a vacuum and in the presence of different gases,” said Tongcang Li, an assistant professor of physics and astronomy and electrical and computer engineering at Purdue University.
