These Levitating Nanodiamonds Are the World's Smallest Disco Balls
In the past, experiments with these floating diamonds had trouble preventing their loss in a vacuum and reading out the spin qubits, said Tongcang Li, a professor of electrical and computer engineering and physics and astronomy professor at Purdue, in a statement. However, in our work, we successfully levitated a diamond in a high vacuum using a special ion trap. For the first time, we could observe and control the behavior of the spin qubits inside the levitated diamond in high vacuum."
