Researchers Demonstrate New Superconducting Circuit Design That Could Advance Topological Quantum Computing

Researchers experimentally demonstrated a new superconducting circuit architecture that reproduces a key gauge symmetry proposed for future topological quantum computing systems. The device validated the fundamental building block of a theoretical architecture that could eventually support topologically protected quantum states when assembled into larger lattices. The research team included scientists from the University of Chicago, Purdue University, Boston University and AppliedTQC. Researchers have experimentally demonstrated a new type of superconducting quantum circuit that reproduces a long-predicted gauge symmetry believed to be a key ingredient for future topological quantum computers, according to a recent study. The researchers report this marks an early but significant step toward hardware designed to protect quantum information through its underlying physics…
