- Quantum information science
**Quantum information science**concerns information science that depends on quantum effects in physics. It includes theoretical issues in computational models as well as more experimental topics in quantum physics including what can and cannot be done withquantum information . The term**quantum information theory**is sometimes used, but it fails to encompass experimental research in the area.Subfields include:

* Quantum computing, which deals on the one hand with the question how and whether one can build aquantum computer and on the other hand, searchingalgorithms that harness its power (seequantum algorithm )

* Quantum computational complexity

*Quantum cryptography and its generalization,quantum communication

*Quantum error correction

*Quantum communication complexity

*Quantum entanglement , as seen from an information-theoretic point of viewQuantum teleportation is one well-known quantum information processing operation which reliably transfers an unknown quantum state from one point to another distant point, destroying the original state in the process.**References*** Nielsen, M.A. and Chuang, I.L.

The quantum information group at the University of Leeds is engaged in researching a wide spectrum of aspects of quantum information. This ranges from algorithms, quantum computation, to physical implementations of information processing and fundamental issues in quantum mechanics. Also contains some basic tutorials for the lay audience.
