Show HN: Quantum Coin Flip - The most random coin flip on the internet
A Show HN web demo generates coin flips by running a single-qubit superposition-and-measure circuit on IBM's quantum hardware, presenting the outcomes as hardware-derived random bits. It is framed as an educational primer on quantum randomness versus classical pseudorandom generation, with cryptography cited as the motivating use case.
Why it matters: Useful as a teaching artifact for demonstrating cloud access to real quantum hardware, but it contributes no new capability — measured qubit outcomes carry device noise and bias, and certified randomness requires protocols well beyond a single Hadamard.

Hey HN!<p>I've created a quantum coin flip demo leveraging IBM's quantum computing tech to explore true randomness. It's a primer on into how quantum mechanics can solve classical computing's randomness limitations, crucial for cryptography and secure systems. Would love your thoughts on its application and quantum computing's future role in tech!
