The first quantum revolution has brought us the classical Internet and information technology. Today, as technology advances rapidly, the second quantum revolution quietly arrives, with a crucial moment for quantum technology to establish large-scale quantum networks. However, solid-state quantum bits (such as superconducting and semiconductor qubits) typically operate in the microwave frequency range, making it challenging to transmit signals over long distances. Therefore, there is an urgent need to develop quantum transducer chips capable of converting microwaves into optical photons in the communication band, since the thermal noise of optical photons at room temperature is negligible, rendering them an ideal information carrier for large-scale spatial communication. Such devices are important for connecting different physical platforms and efficiently transmitting quantum information. This paper focuses on the fast-developing field of optomechanical quantum transducers, which has flourished over the past decade, yielding numerous advanced achievements. We categorize transducers based on various mechanical resonators and discuss their principles of operation and their achievements. Based on existing research on optomechanical transducers, we compare the parameters of several mechanical resonators and analyze their advantages and limitations, as well as provide prospects for the future development of quantum transducers.
第一次量子革命给我们带来了经典互联网和信息技术。如今，随着技术的飞速发展，第二次量子革命悄然来临，这是量子技术建立大规模量子网络的关键时刻。然而，固态量子比特（如超导和半导体量子比特）通常在微波频率范围内运行，这使得长距离传输信号具有挑战性。因此，迫切需要开发能够将微波转换为通信波段光学光子的量子换能器芯片，因为室温下光学光子的热噪声可以忽略不计，使其成为大规模空间通信的理想信息载体。此类设备对于连接不同物理平台和高效传输量子信息至关重要。本文聚焦于光机械量子换能器这一快速发展的领域，该领域在过去十年中蓬勃发展，取得了众多先进成果。我们根据各种机械谐振器对换能器进行分类，并讨论它们的工作原理和成果。基于对光机械换能器的现有研究，我们比较了几种机械谐振器的参数，分析了它们的优缺点，并为量子换能器的未来发展提供了展望。
