Superconducting quantum computing
Goran P. Wendin · Physics World · 2003
Quantum computers are a very special breed of computer that depend on the superposition and entanglement of quantum states. Computer components are getting smaller all the time, and no doubt they will eventually reach the nano-scale where quantum effects start to play a part. But this alone will not make them quantum computers. They will still work pretty much like an ordinary PC, and be able to solve the same limited kind of problems.
