Abstract
We present a new Python package that uses the formalism of geometric quantum complexity to numerically compute metric-dependent geometric cost and control functions associated with preparing a given unitary transformation on a quantum computer. The numerical procedure we implement is presented and discussed. Analyzed quantum circuits include: the quantum Fourier transform for up to four qubits, a random circuit with depth 100, and a circuit for analyzing the evolution of a fermionic chain with several lattice sites.
