Good vibrations for quantum communications: Engineers couple single phonon to single atomic spin

Phys · · 464 words · By Anne J Manning

Researchers at Harvard SEAS have successfully demonstrated the interaction between a single phonon and a single atomic spin in a diamond color-center. This achievement suggests a potential future for quantum acoustics as a means of storing and transporting quantum information.

“Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated, for the first time, a single quantum of vibrational energy interacting with a single atomic spin”
CORROBORATED
Multiple web search results confirm that researchers observed the acoustic Purcell effect where a single quantum of acoustic energy (phonon) had a measurable effect on the atomic state of a spin qubit in diamond. The evidence links this to the Harvard SEAS context via the mention of Marko Loncar's work on phonons and silicon-vacancy centers.

“Led by Marko Lončar, the Tiantsai Lin Professor of Electrical Engineering, the researchers engineered a nanometer-scale mechanical resonator around a single color-center spin qubit in diamond.”
CORROBORATED
Web search results confirm Marko Loncar at Harvard engineers interactions between phonons and single silicon-vacancy centers. Further search results for the Nature paper describe the construction of a microwave-frequency nanomechanical resonator around a colour centre spin qubit in diamond, which aligns with the claim.
