Part 2/11:
At the heart of quantum computing lies a fundamental change in how data is processed. Traditional computers utilize bits that are either zero or one, likened to a light switch that can be on or off. This method, while functional, limits the processing capabilities to binary decisions.
In contrast, quantum computers harness qubits, which can exist in both states simultaneously through a principle known as superposition. Imagine a spinning coin that reflects both heads and tails until you observe it; this phenomenon allows quantum computers to analyze vast sets of possibilities concurrently, exponentially enhancing their computational power.
