         THE QUANTUM WAY OF DOING COMPUTATIONS

   Since the mid nineties of the 20th century it became apparent that one
of  the centuries? most important technological inventions, computers in
general and many of their applications could possibly be further enormously
enhanced by using operations based on quantum physics. This is timely since
the classical roadmaps for the development of computational devices,
commonly known as Moore?s law, will cease to be applicable within the next
decade due to the ever smaller sizes of the electronic components that soon
will enter the quantum physics realm.
Computations, whether they happen in our heads or with any computational
device, always rely on real physical processes, which are data input, data
 representation in a memory, data manipulation using algorithms and
finally, the data output. Building a quantum computer then requires the
implementation of quantum bits (qubits) as storage sites for quantum
information, quantum registers and quantum gates for data handling and
processing and the development of 
quantum algorithms. In this talk,  the basic functional principle of a
quantum computer will be reviewed and a few technologies for their
implementation will be highlighted. In particular, the quantum way of doing
computations will be illustrated by showing how quantum correlations,
commonly known as ?entanglement? can enhance computational processes. Aside
from  their use for quantum computers, these quantum technologies open wide
perspectives for applications in many 
technical areas. Examples such as quantum enhanced metrology and quantum
simulations will be presented.
