我们展示了如何通过将带电悬浮纳米颗粒和微米颗粒与 RLC 电路连接来冷却它们。全电悬浮和冷却适用于各种颗粒尺寸和材料，并将在电气网络系统中实现最先进的力传感。通过探索现实噪声存在下的冷却极限，我们发现在低温环境中无论是被动电阻冷却还是主动反馈方案都可以达到粒子运动的量子状态，从而为悬浮量子机电铺平了道路。
We show how charged levitated nano-and micro-particles can be cooled by interfacing them with an RLC circuit. All-electrical levitation and cooling is applicable to a wide range of particle sizes and materials, and will enable state-of-the-art force sensing within an electrically networked system. Exploring the cooling limits in the presence of realistic noise we find that the quantum regime of particle motion can be reached in cryogenic environments both for passive resistive cooling and for an active feedback scheme, paving the way to levitated quantum electromechanics.
