“Imagine tiny diamonds floating in an empty space or vacuum. Inside these diamonds, there are spin qubits that scientists can use to make precise measurements and explore the mysterious relationship between quantum mechanics and gravity,” explains Li, who is also a member of the Purdue Quantum Science and Engineering Institute. “In the past, experiments with these floating diamonds had trouble in preventing their loss in a vacuum and reading out the spin qubits.
The authors of this paper were mostly from Purdue University and are members of Li’s research group: Yuanbin Jin , Kunhong Shen , Xingyu Gao , and Peng Ju . Li, Jin, Shen, and Ju conceived and designed the project and Jin and Shen built the setup. Jin subsequently performed measurements and calculations and the team collectively discussed the results.
Levitated nanodiamonds with embedded spin qubits have been proposed for precision measurements and for creating large quantum superpositions to test the limit of quantum mechanics and the quantum nature of gravity.century. However, we still do not know how gravity might be quantized,” says Li. “Achieving the ability to study quantum gravity experimentally would be a tremendous breakthrough.
