An enhanced cooling method for the quantum world

https://phys.org/news/2023-01-cooling-method-quantum-world.html

"simple method increases cooling efficiency of even massive objects by order of magnitude... couple vibrating beam to superconducting circuit via magnetic field... attached magnet to beam... When magnet moves, changes flux of superconducting quantum interference device (SQUID)... resonant frequency changes depending on flux, measured using microwave signals... micromechanical oscillator cooled near absolute zweo... change in resonant frequency as function of microwave power is not linear"
