|Objective||In recent years the realm of quantum mechanics has entered the domain of information technology. Enormous progress in the physical sciences and in engineering and technology has allowed us to envisage building novel types of information processors based on the concepts of quantum physics. In these processors information is stored in the quantum state of physical systems forming quantum bits (qubits). The interaction between qubits is controlled and the resulting states are read out on the level of single quanta in order to process information. Realizing such challenging tasks may allow constructing an information processor much more powerful than a classical computer. The aim of this class is to give a thorough introduction to physical implementations pursued in current research for realizing quantum information processors. The field of quantum information science is one of the fastest growing and most active domains of research in modern physics.|

|Content||The course is a theoretical introduction to strong field laser|
ionization of atoms and molecules. Particular focus will be on tunnel
ionization which is behind many recent experiments and applications,
both in chemistry and physics. Common approaches to analyzing
ionization events will be presented, including Keldysh, Strong-Field
and others. The aim is to both understand ionization from a
theoretical perspective and to put into context recent experimental
results. With this in mind, important phenomena created by strong
field ionization, such as high harmonic generation (HHG) and Rydberg
state creation will be explained. Among the fundamental physics
questions addressed will be the much debated question of tunneling
time in ionization, defining tunneling time and relating it to recent
experimental measurement and theoretical literature.
