The present invention discloses a a quantum computing apparatus. The quantum computing apparatus comprises a substrate layer and a patterned layer adjacent and parallel to the substrate layer such that the substrate layer and the patterned layer form a layer stack. The patterned layer comprises an electrically conductive material. The layer stack forms multiple qubits. The quantum computing apparatus further comprises an interposer comprising a rigid connection element mechanically connected to the layer stack, wherein the connection element is substantially planar and positioned in a non-parallel plane to the plane in which the substrate layer is formed, and wherein the connection element comprises a conductive element formed on or in the connection element, preferably a transmission line, for providing an electrical connection to the patterned layer.
