Quantum network technologies based on diamond NV centers

Abstract

Quantum networks are a fundamental technology that enable quantum communication and distributed quantum computing. As a key platform for quantum networks, diamond NV centers have attracted significant attention. This study develops a novel approach for spin qubit control under zero magnetic field, an approach that differs from conventional methods. By integrating this technique with spin-photon interfaces and deterministic Bell-state measurements, we systematically establish the core technologies required for quantum network implementation. This study provides a comprehensive overview of these advancements, incorporating techniques such as quantum entanglement, Bell-state measurement, and quantum teleportation, and discusses prospects for further development.
