Harnessing the power of quantum mechanical systems will have a profound impact on information processing, in particular on computing and cryptography. I will discuss the current state of the field, including recent work on quantum compilers.
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.
The word 'quantum' comes from the Latin word quantus meaning 'how much'. Quantum computing is a fundamentally new mode of information processing that can be performed only by harnessing physical phenomena unique to quantum mechanics (especially quantum interference). Paul Benioff of the Argonne National Laboratory first applied quantum theory to computers in 1981 and David Deutsch of Oxford proposed quantum parallel computers in 1985, years before the realization of qubits in 1995. However, it may be well into the 21st century before we see quantum computing used at a commercial level for a variety of reasons discussed in this paper. The subject of quantum computing brings together ideas from classical information theory, computer science, and quantum physics. This paper discusses some of the current advances, applications, and chal-lenges of quantum computing as well as its impact on corporate computing and implications for management. It shows how quantum computing can be utilized to process and store information, as well as impact cryptography for perfectly secure communication, algorithmic searching, factorizing large numbers very rapidly, and simulating quantum-mechanical systems efficiently. A broad interdisciplinary effort will be needed if quantum com-puters are to fulfill their destiny as the world's fastest computing devices.
