由于微波信号的能量含量很低，单光子级别的微波信号的测量具有极大的挑战性。在单光子光学力学和混合光学机械系统最新进展的指导下，我们提出了一种多模光机械换能器，它可以通过将微波信号绝热传输到光学频域来检测显著低于单光子水平的强度，然后在光学频域进行测量。文中还讨论了本征量子涨落和热涨落的影响。
Because of their low energy content, microwave signals at the single-photon level are extremely challenging to measure. Guided by recent progress in single-photon optomechanics and hybrid optomechanical systems, we propose a multimode optomechanical transducer that can detect intensities significantly below the single-photon level via adiabatic transfer of the microwave signal to the optical frequency domain where the measurement is then performed. The influence of intrinsic quantum and thermal fluctuations is also discussed.
