A dream machine for the 21st century, a quantum computer

Research output: Contribution to journalReview articlepeer-review


A quantum computer is a conceptual computer which operates by a vast parallelism and can solve quickly currently unsolvable problems. This paper reviews why the quantum computer attracted so much interest and briefly introduces important key principles of quantum computation by using, as an example, solution NMR (nuclear magnetic resonance). I also discuss superconductor and semiconductor systems in which quantum interaction effects may lead to the realization of practical quantum bits. These quantum systems have received much interest due to their scalability-an attractive feature of solid-state systems.
