Quantum Information with Trapped Ions
Experimental Quantum Information

Experimental Quantum Information

Informationprocessing according to the rules of quantum mechanics holds an enormous potential for future technologies. Realized in the Lab, it allows to experience quantum mechanics intuitively.
The lecture addresses all students, who want to understand the abstract concepts of quantum mechanics intuitively. We will discuss the most important experimental approaches for quantum information processing. Further ephasis will be given to implementations of the Deutsch-Josza algorithm and teleportation of quantum states.
