Quantum Lings – A LeetCode-style platform for quantum computing

Hacker News

Hi HN, I’m Yongcong Luo, the creator of Quantum Lings. I've been fascinated by quantum computing for a while, but I always found the learning curve to be incredibly steep. Most resources are either dense academic papers or require complicated local setups with SDKs like Qiskit or Cirq before you can even write your first line of quantum code. There wasn't a simple, interactive way to get hands-on practice with quantum algorithms in the same way LeetCode or HackerRank let you practice for traditional software engineering. So, I built Quantum Lings. It's a browser-based platform with a series of coding challenges designed to take you from basic quantum gates to more complex algorithms like Grover's search. The goal is to make learning quantum concepts more accessible and interactive. Key features right now: * In-browser quantum simulator – no local installation required. You can start coding in seconds. * A growing library of guided problems with tutorials and hints. * Circuit visualizations to help you understand what's happening to the qubits at each step. This is a pilot launch, so the platform is still very new and I have a long list of features and problems I want to add. I'm launching it today because I'm looking for feedback from the community. I would love to hear what you think. Is it useful? What problems would you like to see added? Are there any bugs or things that are confusing? I'll be here all day to answer questions and listen to any and all feedback. Thanks for checking it out!
