摘要：

The search for a practical quantum computer has come one step closer to reality with the creation of a solid-state 'quantum bit', or 'qubit'. A qubit is a two-state quantum system, which offers greater efficiency than the classical computer bit. What makes this latest qubit so exciting is that it can be controlled externally allowing the device to be switched between states.
