Quantum Computing: Disrupting Traditional IT Infrastructure

Quantum computing is the paradigm shift of information processing that can completely impact the conventional information technology infrastructure. Compared to classical computing systems that are based on binary logic and sequential computing, quantum computers use quantum bits, superposition and entanglement to compute complex computations faster than ever before. The present paper discusses the impact of the emergence of quantum computing on traditional IT architectures, software frameworks, data security mechanisms and enterprise computing strategies. The paper addresses the inefficiencies of mainstream infrastructure encountered by quantum-enabled capabilities, in particular, cryptography, large-scale optimization, simulation, and data analytics. Encryption standards are currently under critical consideration using the cloud models and high-performance computing to define their vulnerability and flexibility in a post-quantum world. It is also identified that the paper finds the repercussions of quantum computing in cybersecurity and the vulnerability of systems of public-key cryptography and how they are in need of expediency resolutions of quantum-resistant algorithms. In addition, the organizational and infrastructural challenges of quantum adoption, such as cost, scalability, the lack of skills, and compatibility with the legacy systems are discussed. Due to the integration of the results of the recent theoretical advances and practical studies, one can obtain a profound insight into how quantum computing is leaving the laboratory and entering the field of practical use. These results indicate that quantum computing will not necessarily eliminate the classical systems rather it will merely require a fragile re-architecturing of the IT infrastructure to provide quantum computing. The end of the paper is a strong appeal to need to have proactive policy planning, investment on post-quantum technologies and workforce preparations as the tool of providing a successful transition and technology resilience in the quantum era.
