Quantum computing represents a paradigm shift in computational science, offering unprecedented capabilities to solve problems beyond the reach of classical systems. Yet, its implementation and operation involve profound challenges, spanning technical, infrastructural, ethical, and national security dimensions. This article provides a comprehensive analysis of quantum computing systems, examining physical platforms, error correction, qubit connectivity, algorithm design, and industry applications. A case study on national security highlights the urgency of preparing for “Q-Day”—the moment when quantum computers can break classical encryption. Ethical analysis explores privacy, equity, governance, and responsibility, emphasising the need for global frameworks to ensure responsible deployment. By synthesising interdisciplinary perspectives, the study proposes a holistic framework for harnessing quantum computing responsibly, equitably, and securely.

Quantum computers (QCs), which work based on the law of quantum mechanics, are expected to be faster than classical computers in several computational tasks such as prime factoring and simulation of quantum many-body systems. In the last decade, research and development of QCs have rapidly advanced. Now hundreds of physical qubits are at our disposal, and one can find several remarkable experiments actually outperforming the classical computer in a specific computational task. On the other hand, it is unclear what the typical usages of the QCs are. Here we conduct an extensive survey on the papers that are posted in the quant-ph section in arXiv and claim to have used QCs in their abstracts. To understand the current situation of the research and development of the QCs, we evaluated the descriptive statistics about the papers, including the number of qubits employed, QPU vendors, application domains and so on. Our survey shows that the annual number of publications is increasing, and the typical number of qubits employed is about six to ten, growing along with the increase in the quantum volume (QV). Most of the preprints are devoted to applications such as quantum machine learning, condensed matter physics, and quantum chemistry, while quantum error correction and quantum noise mitigation use more qubits than the other topics. These imply that the increase in QV is fundamentally relevant, and more experiments for quantum error correction, and noise mitigation using shallow circuits with more qubits will take place.
