Path toward manufacturable superconducting qubits with relaxation times exceeding 0.1 ms

We are excited to share our results on large-scale fabrication compatible integration of superconducting Transmon qubits. With, so called, overlay Josephson junction approach we were able to fabricate in a fully fab-compatible way qubits with close to state-of-the-art coherence times. We also found that coherence times up to 0.1ms are not limited by losses inside the junction, but rather by microwave losses at the outer surfaces of the device.
