Scientists Reveal Hidden Interface in Superconducting Qubit Material
Brookhaven National LaboratoryResearchers from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and DOE’s Pacific Northwest National Laboratory (PNNL) have uncovered an unexpected interface layer that may be hindering the performance of superconducting qubits, the building blocks of quantum computers. While examining this layer through a combination of imaging techniques and theoretical models, they discovered the underlying cause of puzzling structural differences in qubits.
