Quantum information science

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.
