Classical vs Quantum

Classical computing stores definite bits, while quantum computing manipulates amplitudes that become bits only when measured.

A bit is one lane. A qubit is more like a knob whose final readout is still 0 or 1.

Understand

Bits are definite values; qubits are states with measurement probabilities.

Why it matters

Algorithms use amplitude changes before measurement to reveal useful patterns.

Misconception

A qubit is not simply both 0 and 1 as two stored classical records.

Apply

Use the simulator to compare H once versus H twice.
