Quantum Resonance Core (QRC)

Current quantum communication protocols face fundamental limitations such as cryogenic requirements, complex optical setups, and short coherence times. These issues present significant barriers to building scalable and practical quantum networks. In this paper, we propose a novel solid-state architecture -Quantum Resonance Core (QRC)- designed to overcome these limitations. The QRC integrates millions of Nitrogen-Vacancy (NV) centers into a single chip fabricated on a synthetic diamond film, combining high coherence, scalable integration, and robust photonic interfacing. By exploiting the intrinsic shielding properties of diamond at room temperature -what we define as a quantum shield- our design suppresses decoherence by several orders of magnitude. Microwave-based entanglement generation and integrated photonic waveguides make the QRC a commercially viable candidate for real-time, secure quantum communication.
