Nano-oscillator hits record quality factor
- mikewarot 3y agoIt's not really a nano-oscillator if it's not mechanically part of a chip, in my opinion. If this were a MEMS device that could self-initialize, I'd buy it.. but it's more like a lab full of equipment, with a nanometer sized object trapped inside. Cesium Beam resonators have a really high Q, somewhere around 10^6. Cesium beam optical lattices have a Q of about 10^15, well over the 10^10 Q of this device. For a purely mechanical resonator, strained crystalline nanoresonators with a Q of 10^10 have been described[1] [1] https://www.nature.com/articles/s41567-021-01498-4 https://www.nature.com/articles/s41567-021-01498-4
