According to IBM Research, this is a "3D" superconducting qubit device "where a qubit (about 1mm in length) is suspended in the center of the cavity on a small sapphire chip. The cavity is formed by closing the two halves, and measurements are done by passing microwave signals to the connectors." Although the cavity here is about an inch-and-a-half wide, IBM thinks scaling this kind of system to hundreds or even thousands of qubits.
