Introduction to quantum computing - GeeksforGeeks
May 9, 2023 · Have you ever heard of a computer that can do things regular computers can’t? These special computers are called quantum computers. They are different from the computer you use at home or school because they use something called “qubits” instead of regular “bits”. A bit is like a light switch that can only be on or off, like a zero or a one.
