Description
We report a novel fabrication method for transmon qubits, which are fundamental devices in superconducting quantum computers and circuit quantum electrodynamics. Our approach eliminates the need for time- and cost-intensive electron-beam lithography by employing only photolithography combined with angled deposition. Using this method, we successfully realize Josephson junctions with areas comparable to those fabricated by conventional techniques, and evaluate their performance at low temperatures. The proposed fabrication scheme is expected to be advantageous for quantum electronics in terms of process reproducibility and scalability for large-scale circuit integration.
