Researchers at the RIKEN Advanced Science Institute (ASI) and NEC Smart Energy Research Laboratories have demonstrated coherent quantum phase slip (CQPS) in a narrow superconducting wire of indium-oxide (InOx). The wire is inserted into a larger superconducting loop to form a new device called a phase-slip qubit, with the superconducting layer (the thin wire) sandwiched between insulating layers of empty space.
Specifically, the researchers detected...
