Abstract Classical computing, which has transformed the world in unprecedented ways, has not always been deployed in ways that prioritise ethical values such as fairness, justice, and equity. The Western-focused, Silicon-Valley-centric 21st-century-computing model creates digital ‘haves’ and ‘have-nots’. Quantum computers promise to be exponentially more powerful than classical computers for some classically hard problems, potentially transforming application areas such as chemistry, drug discovery, and machine learning. However, if access and control over quantum computing is not shared equitably, then this may serve to amplify existing inequalities and create even deeper divides. Here we consider some of the possible implications for responsible quantum computing, looking ahead to ways in which the rollout of quantum computing could centre ethical principles such as fairness and equity, in order to prevent the mistakes of the ‘classical-only’ past. The issues raised in this paper will be of interest to those engaged in quantum computing research and to those concerned with the societal implications of this major new technology.

Quantum computing, long considered a theoretical and esoteric branch of physics, is now emerging as one of the most transformative technological frontiers of the 21st century. Drawing upon the strange and powerful principles of quantum mechanics—superposition, entanglement, and interference—quantum computers offer the potential to solve certain classes of problems far beyond the capabilities of classical systems. From revolutionizing drug discovery to transforming cryptography, the long-term implications of quantum computing could rival the digital revolution of the 20th century. This essay provides a comprehensive analysis of the current state of quantum computing, its scientific and technological challenges, the trajectory of future development over the next two decades, and the economic and ethical dimensions that will shape its responsible deployment.
Thematic Area: widening access and inclusion From Schrödinger’s Box to Global Fairness: Ethical Dilemmas in Quantum Computing Abstract: Workshop application In the near future, quantum computing may fundamentally reshape our world: problems that once took years to solve could be unraveled in seconds. Yet access to quantum computing remains scarce, costly, and concentrated in the hands of a few corporations and research alliances. This workshop addresses a central ethical question: who should have access to this emerging resource—and on what moral grounds? We conceptualize quantum computing time as an emergent epistemic good (based on the ideas of Miranda Fricker) within a hybrid landscape: while most computations will continue to rely on classical resources, certain problems will increasingly demand quantum capacity. This hybridity raises questions of fairness, since epistemic advantage will depend not only on technical skill but also on access to scarce quantum infrastructures. Drawing on five perspectives—from medical research and climate modeling to cybersecurity, innovation in the private sector, and global poverty reduction—we explore how existential risks, individual interests, and the common good might be reconciled. As a thought experiment, a fictional global ethics council evaluates competing claims, highlighting the need for justice, inclusion, and ethical foresight in shaping access. Key questions include: What moral obligations arise from treating QC capacity as an epistemic good? How should access be widened to include marginalized communities, the Global South, and underfunded institutions? What principles of fairness and inclusion should guide the governance of this resource before inequalities become entrenched? The goal of the workshop is to collaboratively define ethical principles for allocating quantum computing resources in a hybrid future and to develop recommendations for inclusion policies within quantum education ecosystems—opening Schrödinger’s box not to unleash chaos, but to ensure that quantum futures are guided by ethical insight and shared responsibility. Keywords Quantum education, epistemic goods, access & inclusion, hybrid infrastructures, ethics, global justice
Abstract As quantum computing development advances closer toward achieving fault-tolerant error-corrected realisation, debates on applications, impacts, risks, and benefits of quantum computing are timely and due. While there is awareness of the potential power and complexity of quantum computers, there has been relatively little attention on the social impacts and ethical implications of this technology. In grappling with the social impacts of quantum computing, some stakeholders have turned to applied ethics, specifically (classical) computer and Artificial Intelligence (AI) ethics, for guidance. While computer and AI ethics are useful starting points for evaluating the ethical issues posed by quantum computing, uncritically applying existing sets of ethical principles risks overlooking how quantum computing differs from these technologies. We argue that borrowing of ethical principles and guidelines from AI and computing is inappropriate for several reasons: (1) quantum computing, classical computing, and AI are different technologies with significant material differences; (2) unlike AI and classical computers which have become established, quantum computing is an emerging technology, which has implications on the levels of accessibility and immediate impact in society; and (3) there are significant differences in the way AI and quantum computing have been developed and by whom. We also briefly summarise some of the unique risks and societ al impacts posed by quantum computing. We posit that these reasons support the argument for a new sub-field of quantum computing ethics, which would allow a relevant scholarship to develop and provide guidance as quantum computing technology continues to mature.
Abstract: Quantum computing, an interdisciplinary field blending quantum mechanics and computer science, holds promise to revolutionize computational capabilities. Unlike classical computers, which utilize bits to process information in a binary fashion, quantum computers deploy qubits, capable of existing in multiple states simultaneously due to superposition. This unique property, paired with entanglement, offers unparalleled processing power, positioning quantum computing to tackle problems deemed unsolvable by classical means. While heralded for potential applications in cryptography, drug discovery, and complex modeling, quantum computing faces challenges including decoherence, scalability, and error correction. This paper delves into the foundational principles of quantum computing, its current advancements, the vast applications it could revolutionize, and the significant challenges and societal implications it brings. Through comprehensive exploration, we aim to shed light on both the transformative potential of quantum computing and the hurdles that lay in its path.
Quantum computing, leveraging the principles of quantum mechanics, is emerging as one of the most transformative technologies of the 21st century, promising computational power that can tackle problems once considered unsolvable. Unlike classical computing, which processes data in bits, quantum computing operates using quantum bits or ‘qubits’ that exploit quantum superposition and entanglement, enabling vastly superior processing power. This paper examines the challenges and opportunities presented by quantum computing, focusing on its potential to transform various industries such as healthcare, finance, education, defence, utilities and more. Additionally, the paper explores its environmental implications and impact on sustainability. A literature survey of key research contributions and a discussion of commercial timelines highlight the current state and future of this revolutionary technology. While quantum computing presents immense opportunities, its technical and economic challenges must be overcome for it to reach widespread commercial adoption. The paper concludes with an exploration of the road ahead for this nascent technology. Despite significant challenges, quantum computing offers unprecedented opportunities to transform multiple sectors, making it an essential area for ongoing research.
