DESCRIPTION:Since the mid-nineties of the 20th century\, it became apparen
t that one of the centuries’ most important technological inventions\, c
omputers in general and many of their applications could possibly be furth
er enhanced by using operations based on quantum physics. This is timely s
ince the classical roadmap for the development of computational devices\,
commonly known as Moore’s law\, will cease to be applicable within the n
ext decade. This is due to the ever-smaller sizes of the electronic compon
ents that will enter the realm of quantum physics. Computations\, whether
they happen in our heads or with any computational device\, always rely on
real physical devices and processes. Data input\, data representation in
a memory\, data manipulation using algorithms and finally\, data output re
quire physical realizations with devices and practical procedures. Buildin
g a quantum computer then requires the implementation of quantum bits (qub
its) as storage sites for quantum information\, quantum registers and quan
tum gates for data handling and processing as well as the development of q
uantum algorithms.\n\nIn this talk\, the basic functional principle of a q
uantum computer will be reviewed. It will be shown how strings of trapped
ions can be used to build a quantum information processor and how basic co
mputations can be performed using quantum techniques. In particular\, the
quantum way of doing computations will be illustrated with analog and digi
tal quantum simulations\, which range from the simulation of quantum many-
body spin systems over open quantum systems to the quantum simulation of a
lattice gauge theory.\n\nhttps://indico.fysik.su.se/event/6390/
