Wisconsin–Madison and UC Santa Barbara researchers combined a photonic resonator with a piezoelectric actuator. They demonstrated control of a 780-nanometre laser and used the system to cool rubidium atoms without additional modulators and switches.
The October 14 university account covers a study published September 16 in Nature Communications. It is a laboratory demonstration, not a commercially available quantum computer or sensor.
