A field which is concerned with what we can and cannot do with
quantum information. Subfields include:
- Quantum computing
- [Quantum computational complexity]?
- [Quantum cryptography]?
- [Quantum error correction]?
- [Quantum communication complexity]?
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.
