An adiabatic cycle of parameters in a quantum system can yield the quantum anholonomies, non-trivial evolution not just in the phase of states, but also in eigenvalues and eigenstates. Such exotic anholonomies imply that an adiabatic cycle rearranges eigenstates even without spectral degeneracy. We show that an arbitrarily large quantum circuit generated by recursive extension can also exhibit the eigenvalue and eigenspace anholonomies.
