mechanics-based algorithms and protocols can play an important role in our
nowadays used technical solutions. Quantum computing and quantum communications
is no longer belongs to the world of scientific laboratories since more and
more products are offered by different companies in the market. This
course gives an overview on different areas of quantum computing and communication
including qubits, quantum registers, quantum gates and different quantum
algorithms (Grover, Deutsch-Jozsa, Shor, etc.) and protocols (including quantum
teleportation and quantum key distribution).

State of art of quantum computers: photons,
electron spins, atoms. Existing architecture and current research directions.
the requirements of 1 homework project and 3 short classroom tests.
grade is calculated as follows: result of 1 homework project (40 percent) and
results of 3 short classroom tests (20 percent each).
classroom tests cannot be repeated. Homework project can be submitted later
until the supplement week according to the related university regulations.
Ad hoc meetings with the lecturer.
