Gene Expression Programming for Quantum Computing

We introduce QUANTUMGEP, a scientific computer program that uses gene expression programming (GEP) to find a quantum circuit that either (1) maps a given set of input states to a given set of output states or (2) transforms a fixed initial state to minimize a given physical quantity of the output state. QUANTUMGEP is a driver program that uses evendim, a generic computational engine for GEP, both of which are free and open source. We apply QUANTUMGEP as a powerful solver for MaxCut in graphs and for condensed matter quantum many-body Hamiltonians.
