Optomechanical systems offer a promising route towards frequency conversion between microwave and optical quantum signals. Current theoretical and experimental efforts focus on approaches based on either optomechanically induced transparency (suffering from limited conversion bandwidth) or adiabatic passage (requiring time-dependent control). In my talk, I will present two alternative strategies for optomechanical transduction that avoid these limitations. In the first one, entanglement between two superconducting qubits is generated by using transducers as force sensors; jointly measuring the force with which the qubits act on the transducers leads to conditional generation of entanglement between the qubits. The other approach uses spatially adiabatic frequency conversion in an array of optomechanical transducers, allowing for large conversion bandwidth with time-independent control.
