Optimization of the rotational mode entanglement in a ring-shaped cavity with Casimir forces

Abstract

This research explores the measurement and enhancement of entanglement between two rotational modes generated by rotating mirrors within a ring cavity system. The study specifically focuses on the role of the Casimir force in augmenting the entanglement of these modes. A detailed analysis is conducted to understand the impact of various parameters on the entanglement, including the distances between the external plates and the rotating mirrors ($d_1=d_2$), the radius of the rotating mirrors ($r_1=r_2$), the temperature ($T$), and the areas of the external plates. The findings reveal that the presence of the Casimir force significantly enhances the entanglement between the rotational modes. This research introduces a novel technique for modulating the entanglement of rotational modes through the influence of the Casimir force, presenting new possibilities for advancements in quantum information science.
