Science in Seconds - Quantum Computers

Science in Seconds Know Everything RUMOURS - Quantum Computers Brit Trogen: The futuristic dream keeping physicists and computer geeks awake at night with visions of God-like power is quantum computing. It doesn't exist yet, but every few months we hear reports of a new experiment bringing it one step closer to reality. Quantum computers harness the power of atoms, exploiting the intangible laws of quantum physics to do what I can only describe as magic. While regular computers use bits, encoding information as either a zero or a one, quantum computers use quantum bits, or qubits, which can exist in superposition. In other words, information can either be passed as zero, one, or as both zero and one at the same time, allowing quantum computers to perform many calculations at once. Because of this, quantum computers aren't limited to two states, and have the potential to perform millions of calculations in the same amount of time it would take the computer you're watching right now to complete one, making them more powerful than any of the supercomputers that exist today, running in the teraflops, as compared to measly gigaflops. In simpler terms, imagine you needed to call a friend, and had a hundred numbers, but didn't know which was correct. Your regular computer would have to go through each in turn. But the quantum computer could essentially dial them all at the same time, while only connecting you with the correct number. Like I said, magic. True quantum computers are still a ways off. But hopefully, they'll be perfected just in time to save the world. Because, let's face it, a magic computer probably has a better shot.
