Hamiltonians for Ising-type quantum networks
Päivi Törmä, Igor Jex · Journal of Modern Optics · 2000
We derive Hamiltonians for quantum networks of Ising-type structure. These networks can be composed of simple optical elements such as beam splitters or parameteric amplifiers, similar structures appear also in a variety of systems with many intersecting energy levels. We give exact forms for the Hamiltonians and discuss their implications in certain limits.
