Built a simple state-vector quantum gates emulator in pure C++ (no dependencies) – open for feedback!
Summarize this article with:
Hi everyone! I've been learning quantum computing basics and decided to implement a lightweight simulator from scratch in C++ to better understand state-vector simulation, gates, and measurement. Project: QLEMU Link: https://github.com/nofixing-dev/QLEMU Key features so far: Pure C++ (no external libraries, easy to build on Linux/Windows) Basic gates: H, X, CNOT (planning Z, Phase, Toffoli, etc.) State-vector representation Measurement with Born rule probabilities Simple example in README: creating Bell state and measuring It's very basic/educational/toy-level right now – I built it to experiment with quantum circuits myself. No fancy visualization yet, just console output. Would love to hear: Any obvious bugs or improvements in the code? Ideas for next gates/algorithms to implement (Grover? Deutsch? Simple error models?) How to make it more useful for beginners learning QC? Feel free to clone, run the examples, and roast/critique! 😄 (If this is not the right place – sorry, mods feel free to remove.) submitted by /u/WeOS-Dev [link] [comments]
