The State of Quantum Computing: Applications, Initiatives, Challenges and Ethical Concerns up to 2025

Quantum computing has witnessed a remarkable rise in a century from the theories of Quantum Mechanics to solving real-world problems inside and outside the labs. Experimental quantum computation power has been tested to outperform classical computational power by a wide margin [1]. The work presented here highlights the experimental and commercial state-of-the-art applications of quantum computing from 2016 to 2025. The gathered data includes domains of usage, methods, tools, initiatives, inter-governmental cooperation, quantified results and limitations. In recent times, quantum computing has found applications in diverse areas, including agriculture, defense, energy, finance, healthcare, infrastructure, manufacturing and technology. The purpose of this study is to identify the first of its kind use cases of quantum computers and analyze the outcomes.
