The cavity-optomechanical radiation pressure interaction provides the means to create entanglement between a mechanical oscillator and an electromagnetic field interacting with it. Here we show how we can utilize this entanglement within the framework of time-continuous quantum control, in order to engineer the quantum state of the mechanical system.

We investigate the optomechanical properties of tensile-strained ternary InxGa1xP nanomembranes
grown on GaAs. This material system combines the benefits of highly strained membranes, similar to
those based on stoichiometric silicon nitride, with the unique properties of thin-film semiconductor
single crystals, as previously demonstrated with suspended GaAs. Here, we employ lattice mismatch
in epitaxial growth to impart an intrinsic tensile strain to a monocrystalline thin film (approximately

Photonics is a promising platform for quantum technologies. However, photon sources and two-photon gates currently only operate probabilistically. Large-scale photonic processing will therefore be impossible without a multiplexing strategy to actively select successful events.
