Quantum computing offers a new paradigm for advancing high-energy physics research by enabling novel methods for representing and reasoning about fundamental quantum mechanical phenomena.Realizing these ideals will require the development of novel computational tools for modeling and simulation, detection and classification, data analysis, and forecasting of high-energy physics (HEP) experiments.While the emerging hardware, software, and applications of quantum computing are exciting opportunities, significant gaps remain in integrating such techniques into the HEP community research programs.Here we identify both the challenges and opportunities for developing quantum computing systems and software to advance HEP discovery science.We describe opportunities for the focused development of algorithms, applications, software, hardware, and infrastructure to support both practical and theoretical applications of quantum computing to HEP problems within the next 10 years.
Quantum computing isn't merely another step forward in technology; it represents a leap into an entirely new paradigm for understanding information. By harnessing the strange but powerful principles of quantum mechanics, quantum computers use qubits that can exist in multiple states at once, connect instantly through entanglement, and solve certain problems far faster than any classical machine. This paper explores the fundamentals of quantum computing, from its theoretical roots to the breakthroughs and setbacks shaping its present. We examine the engineering and scientific challenges - from fragile qubits to daunting scalability issues - and the immense promise they hold for fields like cryptography, artificial intelligence, drug discovery, and materials science. Finally, we consider the future impact of this technology, both its opportunities and its risks, and how it may redefine industries, research methods, and even our approach to solving humanity's hardest problems. The purpose of this paper is to examine the fundamental principles, developmental trajectory, current challenges, and prospective impacts of quantum computing across scientific, industrial, and societal domains. Given its potential to reshape computational capabilities and address complex global challenges, this study holds significance for researchers, policymakers, and industry leaders seeking to understand and navigate the transition toward quantum technologies.

This century has been marked by an increasing understanding of quantum mechanics, with our knowledge being continuously refined and complicated. As such, the quantum computer’s potential for drug discovery, decryption and financial optimisation has gained increasing traction. With the United Nations declaring 2025 as the International Year of Quantum Science and Technology, the advent of the quantum technologies has drawn closer than many have prepared for. As the global community continues to approach the brink of quantum revolution, exciting opportunities and serious challenges have presented themselves to us. Quantum computers have evolved beyond the technological experiments locked in quantum science laboratories, they have become real, including the experimental creation of room-temperature quantum computing at the Pawsey Supercomputing Research Centre in Western Australia, the radical streamlining of quantum algorithms which calculate the ground state energies of orbital electrons by Nicole Holzmann and her colleagues, and the optimism by firms in their capacity to provide useful commercial applications of quantum computers in less than a decade’s time. As quantum computing continues to gain momentum in its rapid evolution, gaining progress in its abilities, the technology presents great possibilities which can further the endeavours of the global scientific and mathematical communities. However, the risks that quantum computers pose to cryptography, security and privacy, as well as financial assets cannot be ignored. There has been great debate about the timeline that quantum technology will occupy, whether quantum computers will be a commodity within the next 5 years, or if it will take decades before a fully functioning machine is made. It is constantly too early, yet too late to react to quantum technology. Ultimately, while it is hard to predict when exactly a quantum revolution will take place, it is necessary to acknowledge the slow yet inevitable progress being made in this industry. As such, this whitepaper aims to investigate the fundamentals of quantum computing, giving an overview of the generalised risks and opportunities of quantum computing, based on insights gathered at the Insights Forum held at the Singapore Fintech Festival in November 2024. This is supplemented by specific opportunities and risks present in the finance and banking industry. Finally, this article discusses the specific preparations and preventative measures that companies can take to ensure that they are ready for a post-quantum future.
