Nice explanation ❤

I think get it by avoiding the binary gate there is uninterrupted data flow, the information starts resembling electrical current.

This explains what's already explained everywhere. I thought you could explain with a simple example how qbits perform a simple operation like adding two numbers.

While the coin is spinning it's in the state of superposition(relativity). Translated into the state of quantum thinking [-1,0,1] it's the position 0 while -1 is false and 1 is true. That's how quantum calculation and thinking is working.

If you had access to a quantum computer for one day, what problem would you solve? Cure a disease? Break an encryption? Predict the stock market? Fun fact: Google's Sycamore processor solved in 200 seconds what would take the world's fastest supercomputer 10,000 years!

The spinning coin analogy is such a perfect way to explain superposition, it really helps visualize how qubits differ from classical bits

The spinning coin analogy is the best explanation of superposition I've heard, Quantum computing is mind-blowing, can't wait to see how it revolutionizes AI and medicine in the future. 🤯💻

The spinning coin analogy is such a great way to explain superposition, It's wild to think that quantum computers could eventually revolutionize everything from cybersecurity to medical research. Great breakdown

Forgetting while going through doors or archways has already been studied, interestingly enough. I don't need a quantum computer telling me anything about that!
