Imagine the traditional computer you're using right now. It processes information using bits, which are the basic units of data. A bit can hold a value of either 0 or 1, similar to a tiny switch that is either off or on. This is how classical computers operate—sequentially processing data based on binary values.
Now, let's dive into quantum computing, a groundbreaking concept that redefines how we think about computing. Instead of using classical bits, quantum computers use quantum bits, or qubits. While a bit can only represent one state at a time (either 0 or 1), a qubit has the remarkable ability to exist in multiple states simultaneously due to a phenomenon known as superposition.
