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…
Graph-based emulation of -dimensional curved spaces with superconducting arrays
Mehmet Dede, Guilherme Delfino, André L. G. Mudry +4
We introduce a framework for emulating graphs and, through them, curved spaces of arbitrary dimension, using arrays of superconducting wires. The array consists of two stacked laye…
Topological order and Fractons from Gauging Exponential Symmetries
Guilherme Delfino, Claudio Chamon, Yizhi You
We broaden the scope of quantum field theory by introducing a general class of discrete gauge theories that realize either topological order or fracton behavior across dimensions.…
Cooper-pair splitters as circuit elements for realizing topological superconductors
Guilherme Delfino, Dmitry Green, Saulius VaitiekÄnas +2
Advances in materials and fabrication of superconducting devices allows the exploration of novel quantum effects in synthetic superconducting systems beyond conventional Josephson…
Gauging modulated symmetries: Kramers-Wannier dualities and non-invertible reflections
Salvatore D. Pace, Guilherme Delfino, Ho Tat Lam +1
Modulated symmetries are internal symmetries that act in a non-uniform, spatially modulated way and are generalizations of, for example, dipole symmetries. In this paper, we system…
Fractal Subsystem Symmetries, Anomalies, Boundaries, and Effective Field Theory
Heitor Casasola, Guilherme Delfino, Yizhi You +2
This work reports an extensive study of three-dimensional topological ordered phases that, in one of the directions behave like usual topological order concerning mobility of excit…
