Cloud technology has revolutionized data management by removing time-consuming worries about accessibility and appropriate storage, which can now be managed remotely. However, it may also be claimed that as this technology has advanced, a number of issues about data integrity, secrecy, and authentication have emerged. The authors of this study put forward a hybrid security model that tackles security issues in both cloud and quantum frameworks by combining blockchain technology with quantum cryptography. This strategy targets some of the deficiencies that have been recognized in this context. Confidentiality, integrity, and availability are the three critical dimensions of data that are vital for its protection and security, and cloud technology is known to present numerous challenges regarding these three aspects. Blockchain technology, on the other hand, makes data transparent, decentralized, and unchangeable, which lowers the possibility of unwanted access. The combination of tactics suggested in this article aids in removing several issues that are prevalent in cloud infrastructure, such as data loss, key loss, and man-in-the-middle assaults. In order to improve data security, this study demonstrates the hybrid model's structural design, data transfer, and architectural procedures. The model's research indicates that it has benefits over both a simply created blockchain model and a traditional encryption approach. Additionally, performance benchmarks are provided, proving the model's resistance to cyberattacks in the quantum era. The architecture elevates cloud security and blends in seamlessly with the present cloud status higher by resolving the significant obstacles and is prepared for wider deployment. In order to achieve greater security in today's complex cloud systems, the directed efforts will involve expanding the model to different cloud infrastructures and increasing the system's computing efficiency
