Quantum theory brought new ideas to the theory of information leading which ultimately lead to the theory of quantum information, computation and communication. The lecture introduces the basic concepts of quantum information e.g. quantum algorithms (Shor’s and Grover’s), entanglement, quantum teleportation, quantum cryptography and quantum error correction. It also provides an introduction to modern parts of quantum information, e.g. measurement-based and adiabatic quantum computation and quantum walks.

Syllabus of lectures:

1. Qubit, Bloch sphere, von Neumann entropy

2. Quantum correlations, entanglement and its measures, reduced density operator

3. Quantum teleportation, quantum key distribution

4. Quantum gates and circuits, Deutsch algorithm, universal quantum gates

5. Shor’s factorization, quantum Fourier transformation

6. Grover’s search algorithm

7. Quantum operations, decoherence, POVM measurements

8. Quantum state discrimination

9. Quantum error correction

10. Measurement-based and adiabatic quantum computation

11. Realizations of quantum computing

12. Quantum walks

Syllabus of tutorials:

Solving problems to illustrate the theory from the lecture.
