Unlike traditional computers that rely on bits of information that can be in one of two states (1 or 0), quantum computers manipulate qubits, or units of information tucked inside subatomic particles. That means, they follow the wacky laws of quantum mechanics and so can be in two states at once. This ability allows quantum computers to theoretically store exponentially more information than your everyday laptop. Live Science is here to dissect the latest achievements and discoveries in this bizarre quantum world of computing.
