Description
technical field [0001] The invention relates to the technical fields of two-dimensional material harmonic oscillator preparation, cavity optomechanics, phonon information devices, precision measurement, etc., and particularly relates to a method and device for realizing a phonon maser by using a graphene harmonic oscillator. Background technique [0002] In recent years, the rapid development of laser technology has made great contributions to the field of optical quantum information, which has greatly promoted people's understanding of quantum physics. Compared with photons, phonons (lattice vibration energy quanta) have several unique advantages: First, phonons have shorter wavelengths at the same frequency, that is, phonons are more localized. Compared with microwaves and photons, The transmission speed on the chip is relatively slow, so it is easier to manipulate, and can achieve higher resolution in applications such as imaging and precision processing; the second is th...
