Hi, I'm Snage. I'll be your guide through Quantum Computing.

We begin with "Computing With Amplitudes": what a quantum machine actually does.

300 qubits are described by 2³⁰⁰ numbers. So why do you read back only 300 bits?

How can two coin-flip gates in a row send a qubit back to 0 every time?

And can a quantum computer solve a problem no laptop ever could, given time?
