Measurement-based control, utilizing an active feedback loop, is a standardtool in technology. Feedback control is also emerging as a useful andfundamental tool in quantum technology and in related fundamental studies,where it can be used to prepare and stabilize pure quantum states in variousquantum systems. Feedback-cooling of center-of-mass micromechanicaloscillators, which typically exhibit a high thermal noise far above the quantumregime has been particularly actively studied and has recently been shown toallow for ground-state cooling using optical measurements. Here, we realizemeasurement-based feedback operations in an electromechanical system, coolingthe mechanical thermal noise down to 3 quanta, limited by added amplifiernoise. Counter-intuitively, we also obtain significant cooling when the systemis pumped at the blue optomechanical sideband, where the system is unstablewithout feedback.
