Abstract

This study demonstrates the stability of three-dimensional optical topologies, making them ideal for use in secure communication channels that are prone to noise. The research investigates the stability of link and knot phase singularities when exposed to various types of aberration, providing valuable insights into their performance under perturbation. In addition, the study proposes a highly precise and efficient method for characterising complex bi-photon quantum states, which outperforms traditional quantum state tomography schemes. This novel approach allows for rapid reconstruction of structured entangled photon pairs, enabling researchers to more effectively engineer and utilise these quantum states for a wide range of applications.
