Save valuable research hours by leveraging the power of a universal sample holder. QBoard-II supports any experiment from simple fast turnaround sample characterization to complex microwave-powered experiments. ## Modular Design Improving upon the performance and usability of the original QBoard, QBoard-II features more compact dimensions; new PCB, interposer, and daughterboard designs; and the addition of a shielding lid. A versatile set of mounting brackets ensures full compatibility with popular dilution refrigerators. Easily upgrade from QBoard-I with unchanged connector configurations. ![](https://www.quantum-machines.co/wp-content/uploads/2025/04/Group-196938.png) ## Enhanced Experiment Capabilities Conduct a wide range of experiments with improved signal integrity and reduced noise. The upgraded design with 16 high-density RF and 48 low-frequency RC lines enables transmission from DC to 8 GHz. A new PCB design minimizes losses and crosstalk. This is useful for applications such as readout of superconducting resonators, sub-nanosecond gate-voltage pulses, and high-bandwidth frequency sweeps. ![](https://www.quantum-machines.co/wp-content/uploads/2025/04/QDevil_QBoard-Motherboard-Photoroom-e1717504529497.png) ## Easily Exchangeable Sample Boards The quantum chip is mounted and wire bonded to a daughterboard (6×6 mm, 10×10 mm, and 11×14 mm options). The daughterboard has a 0.5 mm deep gold-plated cavity into which the sample chip can be glued. Two independent four-frequency multiplexed tank circuits for RF readout measurements further enhance the capabilities of the sample holder. ![](https://www.quantum-machines.co/wp-content/uploads/2025/04/QDevil_Daughterboard-and-Interposer-Photoroom-e1717504379393.png) ## Optimal Signal Quality The chip carrier minimizes RF losses and reduces crosstalk, ensuring the quality of your measurements and experiments. Offering radiation protection for both the quantum chip and electrical components, QBoard-II comes with a new shielding lid. The lid fully encloses the sample for proper radiation protection and shields the RC filter components for the lowest noise environment.
