✦ Synopsis

We show that the time evolution of the wave function of a quantum mechanical many particle system can be implemented very efficiently on a quantum computer. The computational cost of such a simulation is comparable to the cost of a conventional simulation of the corresponding classical system. Ultimately the simulation of quantum field theory might be possible on large quantum computers.
