The focus of quantum computing compared to traditional computing lies in its use of quantum bits (qubits) to perform calculations. While classical computers use binary bits (0s and 1s) to process information sequentially, quantum computers leverage the principles of superposition and entanglement to carry out computations simultaneously, exponentially increasing their processing power for certain tasks. This allows quantum computers to tackle complex problems, like cryptography and optimization tasks, at speeds unattainable by classical computers, making them a groundbreaking technology for future innovations.
