Episode Details

Cornell engineers swap argon for krypton gas and cut tantalum qubit deposition temperature from over 400°C to 200°C — a fabrication fix that could matter more for scaling superconducting quantum chips than another qubit-count record. Plus: a Cambridge theory paper narrows what counts as a real quantum advantage, Caltech watches conformal field theory play out on a Rydberg-atom simulator, and a $3B quantum SPAC merger takes its next regulatory step.
