After the transistor, the qubit?
Robert W. Keyes · Computing in Science & Engineering · 2005
Attention is increasingly focused on quantum computing as a path to the continued rapid growth of information-processing technology. But like other physical circuitry, quantum computers must face the uncomfortable fact that man-made objects aren't exact reproductions of idealized devices and aren't invariably perfectly reproducible. The consequences of this imperfection threaten the future of quantum computing.
