WebApr 14, 2024 · High-capacity, long-distance underwater wireless optical communication (UWOC) technology is an important component in building fast, flexible underwater sensing networks. Underwater communication with light as a carrier has a large communication capacity, but channel loss induced by light attenuation and scattering largely limits the … Webthese devices and show that there is an exact mapping between the electronic structure Hamiltonian and the Ising Hamiltonian. The simulation results of the transformed Ising Hamiltonian for H2, He2, HeH +, and LiH molecules match the exact numerical calcula-tions. This demonstrates that one can map the molecular Hamiltonian to an Ising-type
