A basic knowledge of quantum mechanics
Oral discussion
In recent years a new and fertile field of research has emerged which is placed at the intersection of two major lines of scientific development of the last century: quantum mechanics and information theory. The aim of the course is to introduce the fundamental concepts that are the basis of this new and fascinating field of research.
1- The classical computer
The classical Truing Machine. Circuit model of classical computation. Universal logic gates. Computational complexity. Information and energy. The Landauer principle.
2. Introduction to quantum mechanics
Basic postualtes of quantum mechanics. Einstein, Podolsky Rosen paradox. Bell inequalities.
3-The quantum computer
From classical bit to qubit. Universal quantum logic gates. Stability of quantum computing. Logic functions evaluation. Quantum oracles and Deutsch algorithm. Quantum search. Grover algorithm. Quantum fourier transform. Shor algorithm.
4- Quantum communication
Classical cryptography. RSA protocol. Quantum criptography. Protocols BB84 and E91. Dense coding. Quantum teleportation.
5- Current problems and future prospectives
Present experimental realizations. Nonlinear optics, cavity quantum electrodynamics, cold atoms, nuclear magnetic resonance.
