We present the results of application of Evolutionary
Algorithms to the problem of synthesizing quantum circuits
which belong to the class of reversible circuits, represented as an
input/output mapping vectors. The paper specifically focuses on
large quantum circuits where many valid solutions exist in an
exponentially inflating search space. Valid solutions represent
the set of all input vector permutations (arrangements) which
satisfy the circuit specification. The search space for circuits with
large number of variables grows exponentially making it
impossible to discover the set of optimal solutions. The paper
compares three methods for selecting valid solutions of input
vector sequences: 1) randomly, 2) genetic algorithm, 3) Tabu
search. The objective function calculates the number of
elementary quantum gates needed to represent the solution such
that lower number of gates represents better solutions. In
addition to the choice of selection algorithm, we illustrate the
impact of using different partition depths for the Covered Set
Partitions algorithm used to construct valid input vector
sequences
