The q plates were used to enhance the quantum replication of qubits encoded in OAM states. Quantum cloning involves copying information in a quantum state into states, which is crucial for error correction and quantum communication protocols. The experiments demonstrated that when photons traverse these q plates, their polarization states are transformed into OAM states and vice versa, maintaining quantum coherence and entanglement. The effectiveness of these processes was evaluated through photon counting and analysis of interference patterns, which showed accuracy and minimal loss of photons .
