In TR's special issue on the future of computing (Beyond Silicon, TR May/June 2000), we documented efforts to replace silicon with computers based on quantum effects, DNA and organic molecules. Advances reported in each of these areas in August have brought the technologies closer to reality.
A collaboration led by IBM Research's Isaac Chuang (one of the TR100) created an advanced quantum computer that was able to solve in one step a mathematical problem that requires repeated steps in a conventional computer.
