Nonplanar qubit with tunable gauge symmetry
Muqing Yu, Han Bi, Hengli Lo +6
The authors build a non‑planar superconducting qubit using a 3×3 crossbar Josephson array that exhibits a flux‑tunable \(\mathbb{Z}_3\) combinatorial gauge symmetry, and demonstrat…
Nonequilibrium plasmon liquid in a Josephson junction chain
Anton V. Bubis, Lucia Vigliotti, Maksym Serbyn +1
Equilibrium quantum systems are often described by a gas of weakly-interacting normal modes. Bringing such systems far from equilibrium, however, can drastically enhance mode-to-mo…
Microwave radiometry of a quantum-critical, hybrid Josephson array
Kristen W. Léonard, Anton V. Bubis, Melissa Mikalsen +6
Arrays of Josephson junctions can be tuned through anomalous metallic, quantum-critical, and insulating regimes. We introduce a new experimental probe, capturing microwave radiatio…
Hybrid superinductance with Al/InAs
Junseok Oh, Ido Levy, Tyler Cowan +4
We report microwave spectroscopy of Josephson junctions chains made from an epitaxial Al/InAs heterostructure. The chains exhibit superinductance, with characteristic wave impedanc…
Pump Free Microwave-Optical Quantum Transduction
Fangxin Li, Jaesung Heo, Zhaoyou Wang +3
Distributed quantum computing involves superconducting computation nodes operating at microwave frequencies, which are connected by long-distance transmission lines that transmit p…
Room temperature, cavity-free capacitive strong coupling to mechanical motion
Denise Puglia, Rachel Odessey, Peter S. Burns +3
The back-action damping of mechanical motion by electromagnetic radiation is typically overwhelmed by internal loss channels unless demanding experimental ingredients such as super…
