Could silicon be ideal in quantum computing?

(PhysOrg.com) -- "Quantum computing could provide a way to significantly speed up the way we process certain algorithms," Malcolm Carroll tells PhysOrg.com. "The primary issue, though, is that you need a well controlled two-level system." He also points out that problems exist in terms of noise in quantum computing. One of the essentials in some models of quantum computing is utilizing the "spin" of certain electrons. Controlling the spins in GaAs quantum dots has advanced to a fairly sophisticated point, but there is still the issue of noise.
