Quantum information

• Recognise the notions of quantum superposition and entanglement in the context of quantum information.
• Question the nonlocal nature of reality; perform and interpret an experiment testing nonlocality.
• Discuss the concept of quantum communication including quantum teleportation and quantum repeaters.
• Compare different protocols for quantum key distribution and random number generation.
• Explain the main concepts of quantum computing, including gates, circuits, and error correction
• Discuss various quantum algorithms, their implementation, and advantages over classical algorithms
• Describe different quantum technologies for quantum information processing.
• Analyse, discuss and critique articles on quantum information experiments.
• Program a simple quantum computer program using one of the available development toolkits.

The concept of quantum information will be introduced and discussed. Starting from the basic principles of quantum mechanics (superpositions, unitary transformations, and measurements), qubit states, entangled states, and mixed states will be rigorously discussed. Quantum information protocols such as quantum key distribution and quantum teleportation will be introduced. Bell’s inequality will be discussed and tested in the lab. Another subject is quantum computing which includes the discussion of different single and two qubit gates as well as various algorithms including Shor’s factoring algorithm. The different physical technologies for the implementation of quantum information processing will be discussed. Finally, there will be hands-on computational exercises on programming a quantum computer, either by simulation or over the cloud.
