     "If `stim` isn't your quantum circuit package of choice, it may still be possible to utilize CrumPy. Circuits from packages like `cirq` or `qiskit` may be convertible to a `stim` circuit (which can be easily converted to a string for use with `CircuitWidget`). For circuit languages that don't have an existing transpiler that converts to Stim, it may also be possible to convert to [OpenQASM](https://en.wikipedia.org/wiki/OpenQASM), which—while maybe not the most efficient—can be [converted to Cirq](https://quantumai.google/cirq/build/interop#importing_from_openqasm) and finally [converted to Stim](https://github.com/quantumlib/Stim/tree/main/glue/cirq#readme).\n",
