QCage.24 is a versatile sample holder system which fit into most common sample loader puck systems but can also be mounted directly into a fridge with options for both perpendicular out-of-plane and flat in-plane mounting configurations. The QCage.24 is equipped with a low-loss PCB with 24 embedded coplanar transmission lines. It supports up to 10 qubits providing flexibility for a wide range of experiments. The optimized cavity and PCB is optimized to ensure resonance-free transmission up to 18GHz. An EMC tight superconducting enclosure minimizes electromagnetic interference, while an internal flux biasing magnet offers precise control for your experiments.
