•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.
•QuEra achieved an unprecedented 1 error per trillion steps in quantum memory, a critical milestone for reliable quantum computing.
•The breakthrough demonstrates the creation of one reliable logical qubit using just over two physical qubits, significantly reducing hardware demands compared to traditional methods.
•Leveraging neutral atom platforms and co-designed error correction, this work brings the 'Teraquop regime' closer, paving the way for practical quantum algorithms.
