Description
We will present recent experimental progress with micro-machined silicon nanomechanical systems. The interplay between parametric driving, interference and dissipation in a multi-mode cavity electro-optomechanical system can either be used to break time reversal symmetry and act as a compact on-chip microwave circulator [1], to realize bidirectional microwave to telecom conversion, or to deterministically entangle intinerant microwave modes [2]. Observation of such stationary entanglement not only reveals the quantum nature of the mechanical oscillator without measuring it directly, it also represents an important resource for quantum communication and quantum enhanced detection.
