Quantum information theory

Quantum information science is a field of research at the interface of quantum mechanics and computer science.

Its main topics are

Quantum cryptography and its generalization, quantum communication
Quantum computing, which deals on the one hand with the question how and whether one can build a quantum computer and on the other hand, searching algorithms that harness its power (see quantum algorithm)
Quantum entanglement as seen from an information-theoretic point of view

The term quantum information theory is often used, but it fails to encompass experimental research in the area.
