Maximum entanglement of quantum-dot systems with single excitation in the spin van der Waals model

A. Miranowicz, S. K. Ozdemir, M. Koashi +2

Time evolution of entanglement of N quantum dots is analyzed within the spin-1/2 van der Waals (or Lipkin-Meshkov-Glick) XY model. It is shown that, for a single dot initially exci…
