I studied physics at Göttingen, where quantum mechanics was born (Heisenberg, Born, Jordan — 1925). Then 20 years building enterprise software. Far from qubits and wavefunctions. Last year, the centenary year, curiosity pulled me back. I started re-learning quantum computing from scratch. And I ran straight into a wall — not the physics, but the tooling. I tried reproducing a quantum circuit from a research paper. The circuit itself was 15 lines of code. Setting it up took 3 hours: framework version conflicts, missing executable code, incompatible dependencies. I thought: this can't be how everyone works. So I built something — nights and weekends. A free, browser-based tool where you can run quantum circuits across Qiskit, PennyLane, and Cirq. No install. No SDK setup. No credentials. Pick a circuit, click run, see results. 60 seconds. It's called QubitHub. 50 curated circuits — from Bell states to VQE to Grover's search. Three frameworks. Version history. Fork anything. I'm still learning quantum computing. Every week I re-derive a circuit gate by gate, and every gap I find as a learner becomes a feature in the tool. If you work with quantum circuits — as a researcher, student, or just out of curiosity — I'd genuinely love your feedback. Try it → qubithub.co What's missing?
