 Notable examples of software tools for design include pyEPR, KQCircuits and [Qiskit Metal](https://qiskit-community.github.io/qiskit-metal/). For control and data acquisition from quantum processing units, projects such as [ARTIQ](https://github.com/m-labs/artiq), [QICK](https://github.com/openquantumhardware/qick) and [QubiC](https://ieeexplore.ieee.org/document/9552516) leverage FPGAs and pulse-level radio-frequency signals for faster operation.
