Brief Description of the Lecture Proposed 			Caslav Brukner

Title: The Physics of Quantum Information

Subject of the Lecture:

Quantum mechanics is fundamentally distinct from both classical physics and our everyday experience as expressed by the Einstein-Podolsky-Rosen paradox and quantum nonlocality - the fact that a local realistic explanation of  quantum mechanics is not possible. In recent years it was shown that such a radical break-up with classical worldview also opens up possibilities to transfer and process information in a fundamentally novel way. To mention just two examples: Quantum computers would be able to perform certain types of calculations with exponential speedup over any foreseeable classical computer. Quantum cryptography  enables the extraction of  secret cryptographic keys whose security is based on physical laws.

The essential question which will be tackled in the course “The Physics of Quantum Information” is: “How to use the distinctive features of quantum physics against the classical world to enhance the efficiency of computation and communication procedures beyond the limits which are achievable on the basis of classical physics”

The following  themes will be considered in the course:

1.	Basic Quantum Concepts:

1.	Introduction into Information Theory
2.	Quantum Superposition, Qubit
3.	Quantum Entanglement, Quantum Non-Locality
4.	Quantum Non-Cloning Theorem
5.	Bell’s Theorem 

2.	Quantum Communication:

1.	Quantum Super-Dense Coding
2.	Quantum Teleportation
3.	Quantum Secret Key Distribution
4.	Quantum Communication Complexity

3.	Quantum Computation

1.	Quantum Parallelism
2.	Deutsch-Jozsa Algorithm
3.	Groover’s Search Algorithm
4.	Shor’s Algorithms for Factorisation
