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

Subfields include:

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.
