论文摘要
将单光子发射器的量子光学特性与纳米光子和等离子系统中可用的强近场相互作用相结合是创建量子操作和计量功能的有力方法。在这方面,积极和动态调节发射机 - 环境相互作用的能力尤其令人感兴趣。虽然已经证明了热,机械和光学调制,但电气调制仍然是一个杰出的挑战。在这里,我们通过对石墨烯的费米能量的原位调节,对Erbium发射器和石墨烯的纳米层之间的近场相互作用进行了快速的全电气调制。我们证明了25%的发射器与> 1,000倍增加的衰减速率的强烈相互作用,并以高达300 kHz的频率进行电气调节这些相互作用 - 比发射器辐射衰减(100 Hz)快的数量级。这构成了集成量子技术的促成平台,通过集体等离子体发射或具有控制波形的光子发射开放量子纠缠产生的途径。
Combining the quantum optical properties of single-photon emitters with the strong near-field interactions available in nanophotonic and plasmonic systems is a powerful way of creating quantum manipulation and metrological functionalities. The ability to actively and dynamically modulate emitter-environment interactions is of particular interest in this regard. While thermal, mechanical and optical modulation have been demonstrated, electrical modulation has remained an outstanding challenge. Here we realize fast, all-electrical modulation of the near-field interactions between a nanolayer of erbium emitters and graphene, by in-situ tuning the Fermi energy of graphene. We demonstrate strong interactions with a >1,000-fold increased decay rate for 25% of the emitters, and electrically modulate these interactions with frequencies up to 300 kHz - orders of magnitude faster than the emitters radiative decay (100 Hz). This constitutes an enabling platform for integrated quantum technologies, opening routes to quantum entanglement generation by collective plasmon emission or photon emission with controlled waveform.
