Stim Files

: They allow for fast sampling and error analysis of circuits with millions of operations. 2. Electro-Stimulation (E-Stim): Audio & Session Files

, a high-performance library for simulating stabilizer circuits. Always encoded in and consists of a series of instruction lines. Structure: Instructions: Each line contains an operation (e.g., ) followed by target qubits. Use the hash symbol ( ) to add non-semantic notes. Annotations: OBSERVABLE_INCLUDE to define how errors should be tracked for decoding. Getting Started: Install the library via pip install stim Write your circuit in a text editor and save it with the extension. stim files
