Introduction
In the realm of technological innovation, quantum computing stands as a revolutionary frontier with the power to reshape industries and solve complex problems previously thought to be insurmountable. Traditional computers operate using bits, which represent information as either 0 or 1. In contrast, quantum computers leverage quantum bits or qubits, which can exist in a superposition of both states simultaneously. This unique property enables quantum computers to perform certain types of calculations at an exponentially faster rate than classical computers. This article explores the potential applications, challenges, and future prospects of quantum computing.
