Abstract
The casual relationship between two split rays (left and right) circularly polarized beams through the chiral medium is investigated in this article. Using partial transposition and superposition of bell states to investigate entanglement phenomenon between the left and right circular polarization beams through the negativity of eigenvalues. Measurement of partial transposition shows two fluctuated positive and negative eigenvalues with time flow and space variation. The maximum positive and negative value of \(\pm 0.5\) is investigated with the variation of space, time, and system parameters. The existence of negative eigenvalues pointed out entanglement between the birefringent beams. Fluctuation of positive and negative eigenvalues shows fluctuation between separable and entangled states. The theoretical results may be useful for super-dense coding, quantum cryptography, quantum bits, and quantum teleportation of optical technology.
