Quantum information science is an area of study based on the idea that information science 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 and can be confused with a subfield of quantum information science that studies the processing of quantum information.

Subfields include:

• Quantum computing: Studies of how and whether a quantum computer can be built and the algorithms that harness its power (see quantum algorithm)
• Quantum error correction
• Quantum information theory
• Quantum complexity theory
• Quantum cryptography and its generalization, quantum communication
• Quantum communication complexity
• Quantum entanglement, as seen from an information-theoretic point of view
• Quantum dense coding
• Quantum teleportation is a well-known quantum information processing operation, which can be used to move any arbitrary quantum state from one particle (at one location) to another.
