How Does a Quantum Computer Work?

Imagine a coin spinning on a table. While it spins, it is both heads and tails at the same time. A quantum computer works like that! It uses tiny bits called qubits instead of regular ones. Regular bits are like light switches; they are either off (0) or on (1). But qubits can be 0, 1, or both at once.

Because qubits can hold many values together, a quantum computer can try lots of answers simultaneously. Think of it like reading a giant maze by looking at all paths at once instead of walking through them one by one. When the coin stops spinning, it shows you the right path.

Sometimes qubits get linked so that changing one instantly changes the other, no matter how far apart they are. This helps the computer work faster and smarter than your laptop.
