Andreev qubit coupler

Caption

Andreev qubit coupler: The long microwave resonator (a) couples two Andreev qubits (left (b), right (c)). The port in the center of image (a) is the readout port. The magnification of a single nanowire (d) gives an idea of the tiny size of a single qubit. The nanowire is coated with a superconductor (cyan). The actual Andreev bound state, which forms the qubit states, is located in the central white section marked by the red arrow. There is also a similar nanowire on the left quantum device.
