The Efficacy of Quantum Computing in E-Governance and the Public Sector: Statistical Models, Projections, and Predictive Analysis

Abstract

Quantum computing (QC) promises to deliver computational advantages over clas- sical computing for certain classes of problems. In e-governance and public sector functions—such as cybersecurity, policy optimization, service delivery, and administrative decision support—these advantages may translate into improve- ments in efficiency, security, transparency, and scalability. This paper critically ex- amines the current literature, constructs statistical and predictive models, and estimates financial and operational projections to assess the likely impact (positive and negative) of deploying quantum computing in public sector governance over the next 10–20 years. We find that with moderate to aggressive adoption, the benefits, particularly security resilience and efficiency gains, substantially outweigh the costs within a medium-term horizon.
