A quantum-network register is assembled using optical tweezers and optical lattices in an optical cavity to enable scalable quantum information processing. The study demonstrates a two-dimensional array of atoms with individual control, achieving high-fidelity atom-photon entanglement with a generation-to-detection efficiency of up to 90%. The system combines cavity quantum electrodynamics with optical tweezers and lattices to enable precise atomic positioning and quantum interface. The optical cavity allows for efficient photon emission and detection, while the optical lattice minimizes atomic perturbation. The register enables multiplexed entanglement generation, with a success rate exceeding 97% per attempt. The system supports up to six atoms in a two-dimensional array, with fidelity remaining constant across the array size, indicating scalability. The approach provides a route for distributed quantum information processing, with potential applications in secure communication, distributed computing, and precision sensing. The study highlights the importance of scalable multi-qubit registers in overcoming optical losses and errors in quantum networks. The experimental setup includes precise atomic positioning, optical cooling, and quantum state initialization. The results demonstrate the feasibility of a quantum network register with high efficiency and fidelity, paving the way for future quantum communication and computation technologies.A quantum-network register is assembled using optical tweezers and optical lattices in an optical cavity to enable scalable quantum information processing.
