Quantum entanglement is a phenomenon where particles become entangled in such a way that one particle's state instantly influences another's state, regardless of distance. This fundamental feature of quantum mechanics has significant consequences for quantum computers, communication, and cryptography. Recent research has delved into how liquid crystals, particularly q-plates, patterned, non-uniform LC, specifically designed liquid crystal cells with patterns to manipulate photons' quantum properties for various quantum information applications. These q-plates are essential in producing entangled polarization states and orbital angular momentum of photons, transmitting quantum information between distinct photon characteristics, and enabling quantum cloning of orbital angular momentum-encoded qubits . The coupling is essential for creating entangled states where the polarization and OAM of photons are interdependent. This is demonstrated in several key experiments showcasing the quantum capabilities of qplates, as discussed below.
