Figure 1: (a) Three main steps and schematic of the experiment showing two qubits (gray) in distinct copper cavities (orange) separated by 1.3 meters of coaxial cable. As illustrated in panel (b) showing the low-temperature segment of the experimental setup, the cable was curled up such that, in practice, the two qubits are separated by a few centimeters.
