A Recursive Module-Coupling Algorithm for Computing Low-Energy Eigenstates
A recursive module-coupling algorithm, which iteratively treats a system as a composition of locally-coupled smaller modules, with low-energy subspace estimated successively according to the same recursive structure, leading naturally to a recursive quantum variational algorithm, providing a systematic and modular circ...
