Summary

Coupled quantum-dot system in semiconductor is considered to be one of the promising candidates of quantum computer. It will be most desirable that the quantum computing devices are implemented into the same substrate as the widely used LSI circuits. From this viewpoint, the quantum computer of coupled quantum dots of semiconductors is presented concentrating on the controlled-NOT-gate operation. The decoherence time of the quantum computation and the measurement procedure by field-effect-transistor structure are discussed.
