    Optical image of a typical ionic liquid (IL) gated device with a droplet of IL on top of the gate electrode and the oxide channel. The gold squares are pads used to make contact to the device via wire-bonding. On right is the magnified image of the device showing the channel (brownish yellow) and the gold electrical contacts (bright yellow). The contacts on the right and left of the channel are the source and drain contacts. The four other contact are used for 4-wire resistance & Hall measurements. (Credit: IBM)

    A picture of IBM’s “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. Despite the apparent large feature size (the cavity is about 1.5 inches wide) for this single qubit demonstration, the team believes it is possible to scale such a system to hundreds or thousands of qubits.

    A picture of the Silicon chip housing a total of three qubits. The chip is back-mounted on a PC board and connects to I/O coaxial lines via wire bonds (scale: 8mm x 4mm). A larger assembly of such qubits and resonators are envisioned to be used for a scalable architecture.
