Editorial: Beyond the hype: What quantum computing means for organizational cybersecurity

As quantum computing inches closer to practical realization, its disruptive potential has sparked both fascination and concern across industries. While researchers advance qubit stability, fault tolerance and quantum error correction, a more urgent question looms: Are organizations, their security leaders, and their workforce prepared for the quantum age? This editorial offers a grounded assessment of the current state of quantum computing and outlines what cybersecurity practitioners, enterprise architects and organizational decision-makers must begin considering today.Quantum computing leverages principles of quantum mechanics like superposition and entanglement to process information in fundamentally different ways. Traditional computing uses binary digits (0 or 1), while quantum computers use qubits, which can exist in a superposition of both 0 and 1 simultaneously, i.e. as a weighted combination of zero and one at the same time, allowing quantum computers to have infinite states simultaneously (Byrd and Ding, 2024). Quantum computers can evaluate many possibilities at once, leverage entanglement and use interference to find answers faster, making them more efficient for specific complex problems (Marr, 2025; Chipidza et al., 2023).Quantum computing will assist in solving problems that are currently too complex for classical computers. In cryptography, it poses a risk to existing encryption methods, as it could make keys crackable much more quickly (Mashatan and Turetken, 2020; Soller et al., 2025). In healthcare and pharmaceuticals, quantum computers can simulate molecules and chemical reactions with high precision and speed, thereby accelerating drug discovery and materials design (Chipidza et al., 2023). In logistics, quantum optimization will help improve supply chains, flight scheduling, and traffic routing (Chipidza et al., 2023; Quantum News, 2024). Quantum computing can enhance AI by dramatically speeding up computations involved in tasks like training complex machine learning models, searching large datasets and optimizing decision processes. Quantum computing can also help in climate modeling and energy research by enabling precise simulations of natural systems (Devadas and Sowmya, 2025). From optimizing supply chains and financial portfolios to accelerating machine learning and discovering new materials, quantum computing can drive efficiency, innovation, and cost savings across industries. As businesses deal with increasingly large and complex datasets, quantum algorithms offer faster and more accurate solutions, providing a strategic edge (Byrd and Ding, 2024; Soller et al., 2025). Ignoring quantum computing risks falling behind competitors who are leveraging it to gain insights, reduce time-to-market, and unlock entirely new business models.Quantum computing will have a disruptive impact on cybersecurity as it is currently practiced. The current encryption standards for public-key cryptosystems like RSA that are universally used in the industry will fail as quantum systems would be able to break the encryption codes instantaneously (Fajinmi, 2025; Mosca, 2018). However, quantum computing does open a new avenue for security through quantum cryptography, where quantum key distribution could allow uncompromised data transmission. Quantum key distribution (QKD) leverages the behavior of photons and the Heisenberg uncertainty principle such that any attempt to eavesdrop on the transmission disturbs the system and is immediately detectable (Kaur et al., 2025).A key foundational concept of quantum computing is entanglement, where qubits become interconnected such that the state of one instantly affects the other, no matter the distance. This connection means that measuring one entangled particle instantaneously reveals information about its interconnected partner even when separated by large distances. Entanglement enables qubits to exist in multiple states simultaneously, allowing a more complex representation of complex problem spaces, facilitating operations on multiple states at once (Chipidza et al., 2023). QKD uses entangled particles to detect any eavesdropping attempts and guarantee secure data transmission. Since measuring a quantum state inevitably disturbs it, any attempt by an eavesdropper to intercept the key will introduce detectable errors, making the transmission secure. Creating and maintaining entanglement, however, is technically challenging because environmental noise and interactions can easily disrupt it, a problem known as decoherence (Schlosshauer, 2019).Despite the early promise and investments, quantum computing remains in the early stages of development. Current quantum computers are sensitive to noise and environmental interference, which results in errors and limits their reliability. They also require extreme operating conditions, such as ultra-cold temperatures, making them complex and costly to maintain. Also, increasing the number of qubits without sacrificing stability is technically difficult, and hence, they are not yet powerful enough to outperform classical computers on most tasks. There is active research on improving qubit stability, error correction, and scaling technologies. Quantum computing relies on the manipulation of quantum bits, or qubits, which are typically created and controlled using nanoscale structures such as quantum dots, superconducting circuits, or trapped ions (AbuGhanem, 2025). These components must be engineered with extreme precision at the atomic or molecular level, and nanotechnology is enabling the fabrication of the delicate and highly controlled environments required for qubits to function, including isolation from noise and thermal interference. Advances in nanotechnology are also helping the field of quantum computing.From an organizational standpoint, the quantum era demands forward-looking strategic planning, beginning with a comprehensive assessment of quantum readiness – an enterprise-wide evaluation of vulnerabilities across cryptographic systems, supply chains and critical data flows. Far from being a one-time checklist, quantum readiness represents an evolving strategic posture that involves mapping current cryptographic assets, assessing risk exposure across systems and applications and identifying business functions most susceptible to quantum-enabled threats. These assessments enable leaders to uncover dependencies on legacy encryption and to develop phased roadmaps for implementing post-quantum cryptography. To ensure sustained resilience, quantum readiness must be embedded within enterprise risk management practices, IT audit cycles and third-party vendor assessments across the digital ecosystem.Quantum-resilient strategies must be prioritized now to avoid being caught unprepared in the event of a sudden leap in quantum computing capabilities. These include maintaining cryptographic agility, testing hybrid encryption approaches, and engaging with vendors who are already transitioning to post-quantum algorithms. Organizations should also monitor the evolution of NIST’s post-quantum cryptography standardization efforts and begin pilot projects to evaluate implementation feasibility. In parallel, the quantum transition demands urgent attention to workforce development. As the quantum threat grows, so does the need for quantum-aware professionals – not only quantum physicists and engineers but also cybersecurity architects, security analysts and IT risk professionals who understand quantum risk and resilience. Upskilling programs, quantum literacy training and academic-industry partnerships will be crucial to building a quantum-aware workforce.The geopolitics surrounding quantum computing is intensifying as nations recognize its potential to transform economic, military and cybersecurity capabilities. The United States and China are in a race to get ahead in quantum computing and are investing billions into quantum research and development, aiming to secure technological leadership. Quantum computing is seen as a strategic asset, particularly in defense and intelligence, where quantum computing and quantum communication could provide decisive advantages in codebreaking or secure data transmission (Mashatan and Turetken, 2020). This has led to a technological race, where control over quantum intellectual property and talent is becoming a national priority.Future research in quantum computing will focus on key areas, including fault-tolerant architectures (Schlosshauer, 2019) that can run long, complex algorithms without being error-prone, which requires robust quantum error correction and the creation of stable logical qubits. Scientists will also explore new qubit materials (Gyongyosi and Imre, 2019) and architecture, such as topological qubits (Lutchyn et al., 2018), which promise greater coherence and scalability. Another major research direction is quantum networking (Kimble, 2008), which will enable entanglement distribution over large distances, facilitating secure communications and distributed quantum computing.Finally, organizations must recognize that quantum computing, like all transformative technologies, brings with it ethical considerations. The immense power of quantum systems raises profound questions about surveillance, the balance of global power and dual-use risks. The ability to break existing cryptographic protocols may undermine trust in digital infrastructure, jeopardize civil liberties and introduce asymmetric advantages in intelligence and warfare. Additionally, unequal access to quantum technology could exacerbate geopolitical tensions and economic divides. There is also the risk of unregulated commercial use, where the pursuit of innovation may outpace the development of ethical standards. As access to quantum capabilities grows, so must efforts to ensure these technologies are governed responsibly, transparently and with global security and equity in mind. Cross-sector collaboration – among governments, industry, academia and civil society – will be essential to develop normative frameworks and safeguards that guide the ethical development and deployment of quantum technologies.In conclusion, quantum computing is a fascinating and rapidly evolving field that holds future potential; however, it is also beset with several limitations that prevent its manifestation as an economically viable commercial platform. It will remain a military and national priority for the foreseeable future and is at least a decade away from being mainstream. Yet its implications for cryptography and corporate resilience are urgent and unavoidable. Cybersecurity leaders who take early action – by conducting quantum readiness assessments, prioritizing resilient strategies and developing a skilled workforce – can turn this challenge into a strategic advantage. The time to lead is now, not when quantum supremacy dominates the headlines.
