| contents | We present a technical guide to developing a quantum-mechanical system with co-trapped laser-cooled ions and electrons, aiming to utilize this mixed-species system in quantum computing and sensing. We outline a method to control the system's quantum state and provide a blueprint for a forward-compatible design for containing it. The proposed technical solution features a planar configuration with a large trapping volume located at a considerable height above the electrode plane. We detail a manufacturing method using copper-coated, laser-machined glass substrates suitable for a high-power microwave drive signal. We discuss electron state decoherence in this trap and suggest that using superconductive films could enhance trapping abilities, though initial experiments are feasible with the current design. |
