Holographic Laser as a Source of Continuous Variable Entanglement

We study the generation and evolution of continuous-variable entanglement in a holographic laser. The two-level atomic medium is trapped in a ring cavity, and couples with two counter-propagating modes. By simulating the dynamics of the system, our numerical results show that the two-mode continuous variable (CV) entanglement can be realized in the present system even in the presence of cavity loss. This investigation provides a research clue for realizing CV entanglement in a two-level atomic medium, which is simpler than the previous works.
