Figure 4. The figure presents a visual portrayal capturing the intricate process of decoherence in the biphoton state, meticulously illustrated from left to right. Through the utilization of the Wigner probability density function, this figure provides a profound glimpse into the dynamic behaviour of quantum entanglement and its susceptibility to environmental influences
