Overview

• A novel Andreev scanning tunneling microscope employs a superconducting tip to filter out normal electrons and reveal Majorana fermions on UTe₂ surfaces.
• Experimental results definitively demonstrate that UTe₂ is an intrinsic topological superconductor rather than a transient candidate.
• UTe₂’s confirmed status validates its 2019 discovery as a leading material for fault-tolerant quantum computing.
• Harnessing a single topological superconductor could simplify quantum chip design and boost qubit densities compared with multilayer stacks.
• The breakthrough dovetails with industry efforts such as Microsoft’s Majorana1 QPU to develop scalable, topological-core quantum processors.
