Quantum<b> </b>Computing<b> </b>Threats<b> </b>to<b> </b>Cloud<b> </b>Data<b> </b>Warehousing: Future-proofing<b> </b>cloud-based<b> </b>data<b> </b>warehousing<b> </b>againstquantum<b> </b>threats

The advent of quantum computing poses unprecedented challenges to the security of cloud-based data warehousing systems. This paper provides an in-depth exploration of the quantum threats that jeopardize the confidentiality and integrity of data stored in the cloud. Beginning with a foundational overview of quantum computing principles, the document highlights the vulnerabilities introduced by quantum advancements, notably Shor's algorithm and its impact on widely-used encryption methods. Recognizing the urgency of addressing these quantum threats, the paper outlines proactive strategies for future-proofing cloud-based data warehousing. This includes the adoption of post-quantum cryptography, the implementation of quantum key distribution (QKD), and continuous monitoring and updates to security protocols. The importance of industry collaboration, involvement of cloud service providers, and the establishment of best practices and guidelines is emphasized.
