2017 PANIC Winners

  • Nate Earnest & Abigail Shearrow

    “This is a quantum device known as the "0-Pi" circuit. Fabricated in the PNF with interdigitated capacitor fingers with a 75nm pitch, stacked Josephson Junctions, and a 20um deep Silicon etch, this device is the first of a new class of protected superconducting qubits being developed at the University of Chicago in the lab of Professor David Schuster.”

  • Gerwin Koolstra & Ge Yang

    “Using three successive e-beam lithography and deep reactive ion etch steps we were able to carve out this complex electrode geometry for out single electron trap. In out experiment, the microscopes channels (3.5 micron in width) you see here are filled with ultracold superfluid helium.”

    “These are surface acoustic wave resonators fabricated in PNF. A patterned thin film of aluminum forms structures that create, trap, and detect mechanical waves in the substrate. To operate at gigahertz frequencies, we use electron beam lithography to define thousands 250nm wide aluminum lines. These lines also form optical diffraction gratings, giving rise to the colorful pattern. High frequency electrical probes are measuring the central resonator.”
