This New “Sound Laser” Could Measure Gravity With Stunning Precision

Researchers at the University of Rochester and RIT developed a thermomechanically squeezed phonon laser.

The device cuts vibration, fluctuation, and thermal noise, making acceleration and force measurements far more precise.

Lower-noise phonon control could improve sensors for gravity, motion, and quantum navigation.

Potential uses include next-generation quantum compasses, GPS-adjacent tools, and other ultra-precise measurement systems.
