                 Quantum simulation of quantum systems


In the early days of quantum mechanics it has become clear that the 
exponential growth of dimension of Hilbert space required to describe a 
quantum system prevents us to do ab-initio calculations. Feynmann 
suggested solving this problem by using quantum systems for this type of 
calculations, which aimed at determining e.g. ground state properties of 
a quantum mechanical object.
In this seminar presentation a simple quantum computer “program” a phase 
estimation procedure is outlined and applied to solve standard 
quantum-mechanical problems.
To conclude the algorithm we analyze two different methods, that are 
originated from very different types of applications and construct, a 
third, a new one, unifying useful properties of the former methods.
Our final purpose is to explain the new algorithm, to show similarities 
and differences, compared to the earlier ones on the simple model 
example of a harmonic oscillator and radial hydrogen atom.
