This new “phonon laser” could measure gravity more precisely than ever before
AI Summary: Researchers at the University of Rochester and Rochester Institute of Technology have developed a new type of squeezed phonon laser that enables precise control of nanoscale vibrations. This advancement addresses the challenge of noise, which has historically limited the accuracy of laser measurements, by employing a technique called squeezing to reduce thermal fluctuations. The enhanced precision of these phonon lasers could facilitate more accurate measurements of gravity and other forces, potentially advancing the development of quantum compasses as alternatives to GPS. The findings were published in Nature Communications and were supported by the National Science Foundation.
