The work is focused on the investigation of features of quantum dynamics for photons in spaser systems consisting of metal nanoparticles (NP) and semiconductor quantum dots (QDs). The non-classical photon states generation in a three-particle spaser system with nonlinear plasmon-exciton interaction is predicted.

We study the effect of external electric bias on the quantum correlations in the array of optically excited three coupled semiconductor quantum dots. The correlations are characterized by the quantum discord and concurrence and are observed using excitonic qubits. We employ the lower bound of concurrence for thermal density matrix at different temperatures. The effect of the Förster interaction on correlations will be studied. Our theoretical model detects nonvanishing quantum discord when the electric field is on while concurrence dies, ensuring the existence of nonclassical correlations as measured by the quantum discord.
