•Researchers have developed a new architecture for superconducting circuits, replacing traditional 'bandages' with solely airbridges for electrical interconnects.
•The new single-step fabrication process uses gray-scale electron-beam lithography, leading to high-yield and mechanically stable connections.
•Transmon qubits fabricated with this method exhibit relaxation times exceeding 250 microseconds, significantly improving coherence and paving the way for more powerful quantum computers.
