The reporter learned from the China University of Science and Technology that Professor Guo Guoping and associate researcher Deng Guangwei of the school and Tian Lin, professor at the University of California, Merced, have pioneered the introduction of the third among non-near neighboring graphene nanoresonators. As a phonon cavity mode, the harmonic oscillator successfully realizes long-range strong coupling, which creates the conditions for storing and transmitting quantum information with phonon mode as a carrier. The international authoritative academic journal "Nature Communications" published the results on January 26. The nano-harmonic oscillator has the advantages of small size, good stability, high quality factor, and is an excellent carrier for information storage, manipulation, and transmission. Both classical and quantum information can be encoded in the phonon state of the harmonic oscillator. The phonon state can also be used to transmit this information. One of the major challenges in implementing this solution is how to implement adjustable phonon interactions over long distances. In recent years, international academics have tried to use optical cavities or superconducting microwave cavities as transfer coupling media, but due to the large frequency difference and coupling strength Smaller, it is difficult to reach a strong coupling range. In response to this problem, Guo Guoping's research group proposed the idea of ​​using the resonator itself as a phononic cavity mode instead of an optical cavity or a microwave cavity, and designed and prepared a series structure of three graphene nanoresonators. In this device, the resonant frequency of each resonator can be greatly adjusted by the respective bottom metal electrode. Experiments show that in this series structure, the neighboring harmonic oscillator can reach the strong coupling interval. When the frequency of the intermediate harmonic oscillator is adjusted to be close to the resonant frequency of both ends of the harmonic oscillator, a large pattern appears between the two ends of the harmonic oscillator. Split, and the split value can be controlled by controlling the frequency of the middle harmonic oscillator. Using the theoretical analysis of the optical Raman process, the research team obtained the equivalent coupling strength of the two-terminal harmonic oscillator and its relationship with the detuning amount. The experimentally found that the measured equivalent coupling is in good agreement with the theoretical results. According to reports, this experiment for the first time achieved non-near-neighbor coupling in graphene nanoresonators, which has important impetus for research in the field of electromechanical harmonic oscillators, and created conditions for the storage and transmission of quantum information using phonon mode as a carrier. Fluid Bed Dryer is also called fluidized bed dryer. Since its application for more than 30 years, it has been continuously developed and improved.
