• Abstract: As a quasiparticle formed by light and excitons in semiconductors, the exciton-polariton (EP) as a quantum bus is promising for the development of quantum interconnect devices at room temperature. However, the significant damping of EPs in the material generally causes a loss of quantum information. We propose a mechanism to overcome the destructive effect of a damping EP on its mediated correlation dynamics of quantum emitters (QEs). Via an investigation of the near-field coupling between two QEs and the EP in a monolayer MoS$_{2}$ nanodisk, we find that, with the complete dissipation of the QEs efficiently avoided, a persistent quantum correlation between the QEs can be generated and stabilized even to their steady state. This is due to the fact that, with upon decreasing the QE-MoS$_2$ distance, the QEs become so hybridized with the EP that one or two bound states are formed between them. Our result supplies a useful way to avoid the destructive impact of EP damping, and it refreshes our understanding of the light-matter interaction in absorbing medium.

  Quantum surface effects (QSEs) of the metal contribute additional loss sources to the surface plasmon polariton (SPP) Here, we investigate the non-Markovian dynamics of quantum emitters coupled to a common SPP in the presence of the QSEs. We find that, as long as the QE-SPP bound states favored by the QSEs are formed, a dissipationless entanglement among the QEs is created.

  We propose to tailor the local density of states (LDOS) of plasmonic resonances by integrating with a photonic cavity operating at a chiral exceptional point (CEP) A quantized few-mode theory is employed to reveal that the LDOS of the proposed hybrid cavity can evolve into sub-tzian lineshape, with order-of-magnitude linewidth narrowing. This results in the enhanced coherent light-matter interaction accompanied by the reduced dissipation of polaritonic states.

  A quantum simulation of magnetism in trapped-ion systems makes use of the crystal vibrations to mediate pairwise interactions between spins. These interactions can be accounted for by a long-wavelength relativistic theory, where the phonons are described by a coarse-grained Klein-Gordon field. We show that thermal effects, which can be controlled by laser cooling, can unveil this flow through the appearance of thermal masses in interacting QFTs.
