The physical and engineering limitations of current quantum devices are driving the development of modular architectures and quantum networks to enable large-scale quantum computers. This article aims to present a literature review on modular architectures in quantum computing. The study aims to present and discuss the main hardware platforms—including superconducting qubits, trapped ions, neutral atoms, and photonic qubits—and analyze how quantum modules can be interconnected with distributed entanglement methods, quantum repeaters, and logic gate teleportation, as well as cost and latency models for distributed quantum operations. Scalability aspects and practical physical implementation challenges are examined in light of proposals and case studies of real modular architectures, such as the IonQ and Honeywell (Quantinuum) approaches with trapped ions and Xanadu with photonics. Finally, we compare the approaches of different platforms and discuss ways to overcome technical obstacles toward modularly scalable and fault-tolerant quantum computers.
