Fermi-Bose Systems, Macroscopic Quantum Superposition States and Entanglement

  • Yorick Hardy
  • Willi-Hans Steeb


We study the entanglement of states of a simple Fermi-Bose system. The Hilbert space is C2 ⊗ l2 (N). An explicit expression is given for the entanglement. We consider number states, coherent states and macroscopic quantum superposition states in the product system. Explicit formulas for the entanglement are also given in each of these cases.
