New tool helps improve quantum computing circuit component

Researchers use a new tool to help improve a key component in commercially produced quantum computing circuits. The team of scientists from the U.S. Department of Energy's (DOE) Ames National Laboratory in partnership with the Superconducting Quantum Materials and Systems Center (SQMS), a DOE National Quantum Information Science Research Center led by Fermilab, used the terahertz SNOM microscope, originally developed at Ames Lab, to investigate the interface and connectivity of a nano Josephson Junction (JJ).
