QDevil, Quantum Machines." --- # QBox ![](https://www.quantum-machines.co/wp-content/uploads/2025/04/QdacII-1.png) ## Highly Reliable 24-Channel Breakout Box Flexible shielded breakout solution [ Get the Spec Sheet ](/request-the-qbox-spec-sheet/) [ Request a Quote ](https://www.quantum-machines.co/request-a-quote-qbox/) ##### QBox is a fully shielded breakout box specialized for electronics labs and low-temperature experiments. QBox extends the cryostat Faraday cage from a 24-pin Fischer connector to a convenient 24-channel BNC connector panel. ## Simplifying the Measurement Process All wiring inside the QBox is done in twisted pairs for the best noise immunity. Switches enable connecting each channel directly to the ground or a common bus, significantly simplifying ESD-sensitive multi-terminal device measurement ![](https://www.quantum-machines.co/wp-content/uploads/2023/04/QBox.2.png) ## Easy to Set Up QBox helps protect samples with a flexible, low-noise cable assembly, which extends the cryostat shield to the QBlox breakout box. With a common bus channel, it’s easy to connect, for example, a sensor or a fixed resistor, to numerous channels. ![](https://www.quantum-machines.co/wp-content/uploads/2023/04/QBox-cable.png) ## Customers’ Success Using QFilter ![](https://www.quantum-machines.co/wp-content/uploads/2023/07/naturecommunicationsweb-637598726191877261-1024x375.jpg) #### Real-time two-axis control of a spin qubit Feb 2024 [ Read More ](https://www.nature.com/articles/s41467-024-45857-0) ![](https://www.quantum-machines.co/wp-content/uploads/2021/10/arxiv-logo-800.png) #### Spin-degeneracy breaking and parity transitions in three-terminal Josephson junctions Jul 2023 [ Read More ](https://arxiv.org/abs/2307.06715) ![](https://www.quantum-machines.co/wp-content/uploads/2021/10/arxiv-logo-800.png) #### Flip-chip-based fast inductive parity readout of a planar superconducting island Jul 2023 [ Read More ](https://arxiv.org/abs/2307.06718) ## Why Leading Experts Worldwide Choose Quantum Machines ![](https://www.quantum-machines.co/wp-content/uploads/2024/01/Princeton.jpg) ### Disentangling Losses in Tantalum Superconducting Circuits “QM’s chip packaging solutions are exquisite pieces of engineering that have enhanced our resonator Q-factors to as much as 200 million.
