Abstract : We study the entanglement measured by concurrence in one-, two- and three-dimensional arrays of molecular dipoles entangled by the dipole-dipole interaction and subject to an electrostatic field. We show that the entanglement can be tuned and controlled by varying the Stark energy splitting of the 0 and 1 states of the molecular dipoles, the dipole-dipole coupling strength, the temperature, and the orientation of the external electric field with respect to the array. We also developed the trace minimization algorithm for exact calculations of eigenvalues and eigenvectors of large lattices (in billions ) and developed new quantum algorithms to solve complex chemistry problems such as global optimization and excited states of molecules.
