Zusammenfassung:I present an overview of the paradigm of quantum computing that is emerging as a result of recent advances in a variety of fields, including fundamentals of quantum mechanics, information theory, quantum optics and atomic physics. The essentials of a practical quantum computer are discussed and a few algorithms that may be implemented on such a computer are presented. The advantages of quantum computers over classical ones are touched upon. A brief discussion on quantum teleportation and entanglement is also included in this article.
