I've been learning quantum computing on the side for a few months. The thing that kept tripping me up wasn't the math — it was how often "canonical" circuits from papers and tutorials would fail quietly. Silently broken Hamiltonians. Reversed bit orders. Post-deprecation API drift. You run the code, get a plausible-looking number, and have no way to tell if it was right.

So I started building a personal library where every circuit is checked against its reference output before it's listed. That's now open to browse at https://qubithub.co?utm_source=nostr&utm_medium=social&utm_campaign=m25-library-open&utm_content=personal

No signup required — 50+ curated circuits across Qiskit, PennyLane, and Cirq.

A few things I'm happy about:

- Readable URLs — every circuit lives at qubithub.co/{owner}/{name}, no UUIDs in the shareable link
- Audited — every circuit verified against its reference output (the ones I had to fix are a separate post)
- Multi-framework — the same algorithm can show up in Qiskit, PennyLane, and Cirq side by side, so you can compare implementations in one place

Sign-up's open today — you get star and save. Creating your own circuit is still invite-only while I stabilize the builder flow; drop me a line after you sign up and I'll flip the switch as slots free up. In-browser execution is the next thing I'm finishing — separate post when it's live.

Six months in, this is the thing I wish had existed when I started. Reply with what you'd want to see next.
