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!

I love that you put together a great explanation to go with it! Well done!

I was following it ok until I reached the section around "basis state". It doesn't actually explain what a "basis state" is.

A basis state would be one of the fundamental states a quantum thing can be in. A classical computing bit has states of 1 and 0 that are analagous to |1> and |0> basis states in a quantum state. A quantum bit would be in a mxture of both.

That makes sense. It's a bit complex, but if you're interested, you can learn more here: https://quantum.country/qcvc

Gotta love quantum computing false fronts :)

Also, modulo a successful coin-in-the-middle attack.
