Quantum Coin Flip - The most random coin flip on the internet
Hey HN! 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!

In plain words
Quantum Coin Flip is an educational demo that uses IBM's quantum computing technology to generate random coin flip results. It shows how quantum mechanics can produce true randomness, addressing limitations of classical computing's pseudo-random methods. The tool is designed for people interested in understanding quantum computing's practical applications in cryptography and secure systems.

Flip a coin that harnesses the inherent randomness of the universe (and learn about Quantum Computing too)
If you clicked that coin, you just witnessed a quantum coin flip; the most random coin flip on the internet. How do computers pick (pseudo)random numbers? While this task is seemingly simple, there’s a whole world of complexity beneath the surface. This complex stuff matters. Computers are built on ‘bits’, or little electrical switches that can be either on or off. In a sense, computers are valuable only because they are NOT random at all. Chip processors have invested billions over decades to ensure that their bits are completely deterministic so that our cat videos will load reliably. Take a second to think about the basic logic gates, and how you would build instructions that result in a…from quantumcoinflip.com

Play with real quantum physics in your browser2025 · quantum.orgsoft.org · ▲156I 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...
Quip NetworkApr 2026 · quip.network · ▲75Hey HN. I'm Colton (YC S21, ex-Acorns), one of the founders of Postquant Labs. My cofounder Richard is a cryptographer out of Draper Labs and DARPA. We're building Quip.Network, the first distributed quantum compute network. We just opened our testnet and wanted to share it here. The basic problem: quantum hardware is here and already competitive on certain optimization problems, but for most people, there's no way to access it. The machines cost millions and the hardware and research are gated by the companies who own them. Also, quantum providers regularly have machines sitting idle…
