In the quantum world, things behave in unexpected ways. A qubit, unlike a classical bit, can represent both 0 and 1 at the same time. To better understand this, imagine a spinning coin. Before it lands on heads or tails, it’s in a state of uncertainty—both heads and tails are possible. Similarly, a qubit in superposition represents both possibilities (0 and 1) at the same time, until it is measured.

This capability allows quantum computers to handle vast amounts of data simultaneously, giving them an advantage in solving complex problems. When you scale this to multiple qubits, the number of possible states grows exponentially.
