Hi! I built this to teach myself how a quantum circuit simulator works. It's about 1000 lines of Python, aiming to be understandable more than being fast or robust. It's not meant to compete with anything else - just a personal project to really get clear on the under-the-hood theory of qubits and quantum gates.

Hello! I’m an engineer who has spent the majority of my career building financial systems and ledgers in fintech. A theme across those years was how painful traditional accounting software was to use, so I set out to build something better with Quanta. The best way to get started was by building software that would enable the best full-service accounting experience, as well as help business owners understand their business. If you have a software business, I’d love for you to check out our free trial. Any feedback appreciated. Thank you!

I wanted to make the simplest app to introduce myself and others to quantum computing. Introducing, Schrödinger's Coin. Powered by a simple Hadamard gate[0] on IBM quantum, with this app you can directly interact with a quantum system to experience true randomness. Thoughts? Could you see any use cases for yourself of this? Or, does it inspire any other ideas of yours? Curious what others on HN think! [0] https://en.wikipedia.org/wiki/Quantum_logic_gate#Hadamard_ga...
