可扩展量子网络需要具备芯片集成、电信波段兼容以及灵活检索能力的量子存储器。纳米加工机械谐振器满足这些标准。它们提供光学和机械模式的独立可调性、长寿命声子态以及超越原子系统的设计灵活性，使其成为实用集成量子存储器的有力候选。在此，我们展示了一种基于光机械诱导透明（OMIT）并在机械基态附近运行的片上吸收式光机械存储器，用于电信波段光子。该器件存储电信波段光子，展示了在少光子水平下与外部光子源的兼容性，同时支持按需检索。通过将器件置于20 mK的稀释制冷机中并定制控制场以抑制光学加热，我们在存储过程中实现了仅0.32的极低声子占据数。我们的结果为可扩展的基于声子的量子存储器件奠定了基础，并为将机械系统集成到实用量子网络架构中开辟了新途径。
英文摘要
Scalable quantum networks require quantum memories that are chip-integrated, telecom-band compatible, and capable of flexible retrieval. Nanofabricated mechanical resonators meet these criteria. They offer independent tunability of optical and mechanical modes, long-lived phonon states, and design flexibility beyond atomic systems, making them strong candidates for practical integrated quantum memory. Here, we demonstrate an on-chip, absorptive optomechanical memory for telecom-band photons, based on optomechanically induced transparency (OMIT) and operating near the mechanical ground state. The device stores telecom-band photons, demonstrating compatibility with external photon sources at the few-photon level, while enabling on-demand retrieval. By placing the device in a dilution refrigerator at 20 mK and tailoring the control field to suppress optical heating, we achieve a remarkably low phonon occupancy of just 0.32 during the storage process. Our results lay the groundwork for scalable, phonon-based quantum memory devices and open new avenues for integrating mechanical systems into practical quantum network architectures.
