Quantum Computing Creation

<Prem Kumar>, a professor of electrical engineering and computer science at Northwestern University, and his team have shown that they can create a quantum logic NOT gate within an optical fiber. Quantum logic with laser beams, that passed through the air have been built before. Because the gate is within fiber, it could be part of a circuit that relays information securely, over hundreds of kilometers of fiber. This gate is one of the building blocks needed to build a <quantum computer>.
