Abstract

Entangled quantum states are an important element of quantum information techniques. We determine the requirements for states of quadrupolar nuclei with spins >1/2 to be entangled. It was shown that entanglement is achieved at low temperature by applying a magnetic field to quadrupolar nuclei possessing quadrupole moments, which interact with the electricfield gradient produced by the charge distribution in their surroundings.
