Query: Entanglement in a quantum neural network based on quantum dots   We studied the quantum correlations between the nodes in a quantum neural
network built of an array of quantum dots with dipole-dipole interaction. By
means of the quasiadiabatic path integral simulation of the density matrix
evolution in a presence of the common phonon bath we have shown the coherence
in such system can survive up to the liquid nitrogen temperature of 77K and
above. The quantum correlations between quantum dots are studied by means of
calculation of the entanglement of formation in a pair of quantum dots with the
typical dot size of a few nanometers and the interdot distance of the same
order. We have shown that the proposed quantum neural network can keep the
mixture of entangled states of QD pairs up to the above mentioned high
temperatures.
