InAs-Al hybrid devices passing the topological gap protocol

1 min read

Materials-and-device milestone for Microsoft’s InAs-Al Majorana program. Reports hybrid devices that pass the topological gap protocol, providing evidence consistent with a topological regime and establishing the device quality needed before tetron-style fusion or parity-readout experiments.

Key Results

  • Several devices pass the topological gap protocol.
  • Extracted topological gaps are reported in the 20-60 eV range.
  • Establishes a prerequisite materials/device milestone, not a demonstrated logical tetron qubit.
