Abstract
The Fock space of a system of indistinguishable particles is isomorphic (in a nonunique way) to the state space of a composite, i.e., many modes, quantum system. One can then discuss quantum entanglement for fermionic as well as bosonic systems. We exemplify the use of this notion—central in quantum information—by studying some, e.g., Hubbard, lattice fermionic models relevant to condensed matter physics.
