Original Kurzfassung:
Classical simulations of quantum computations are
vital for the future development of this emerging technology.
To this end, decision diagrams have been proposed as a complementary technique which frequently allows to tackle the inherent
exponential complexity of these simulations. In the worst case,
however, they still cannot escape this complexity. Additionally,
while other techniques make use of all the available processing
power, decision diagram-based simulation to date cannot exploit
the many processing units of today?s systems. In this work, we
show that both problems can be tackled together by employing
a hybrid Schrödinger-Feynman scheme for the simulation. More
precisely, we show that realizing such a scheme with decision
diagrams is indeed possible, we discuss the resulting problems in
its realization, and propose solutions how they can be handled.
Experimental evaluations confirm that this significantly advances
the state of the art in decision diagram-based simulation?
allowing to simulate certain hard circuits within minutes that
could not be simulated in a whole day thus far.
