Quantum information science
From Freepedia
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 including what can and cannot be done with quantum information. The term quantum information theory is sometimes used, but it fails to encompass experimental research in the area.
Subfields include:
- Quantum computing
- Quantum computational complexity
- Quantum cryptography and its generalization, quantum communication
- Quantum error correction
- Quantum communication complexity
- 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 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.
