Abstract

To promote the future quantum network, we demonstrate an electrically controlled optomechanical entanglement switch in a hybrid opto-electromechanical device, which consists of an opto-mechanical cavity capacitively coupling a variable capacitor, where a nanomechanical oscillator acts as an interface between the cavity and capacitor. In the device, the effective quality and detuning of the cavity can be adjusted by the voltage on the capacitor. Based on the sensitivity of the entanglement to the effective cavity detuning, by changing the voltage, the optomechanical entanglement can be electrically turned on or off. This integrated structure of entanglement switch will excite a development trend and implementation prospect toward integration and miniaturization of quantum module devices in the future quantum network.
