Al/AlOx/Al Junctions for Quantum Devices
iQnite provides wafer-scale Al/AlOx/Al Josephson junction fabrication for superconducting quantum devices. Built on extensive process optimization, our junction platform supports feature sizes from ~100 nm to a few micrometers, with normal-state resistance tunable from approximately 25 kΩ to 300 Ω.
Device Performance
From Junction Process to Quantum Chip Prototyping
Combined with iQnite’s superconducting base-layer fabrication capabilities, this junction process enables high-quality transmon and fluxonium qubits, with demonstrated coherence times reaching approximately 130 μs for transmons and 1.3 ms for fluxonium qubits.
From junction process development to integrated superconducting device fabrication, iQnite supports customers moving from design validation to reliable quantum chip prototyping.
