Quantum Computing holds the potential to change our world. Following the quantum wave, software engineers have recognised the opportunity to establish a new discipline of Quantum Software Engineering. Despite the significant progress achieved, Quantum Computing's widespread adoption still faces critical hurdles. In this paper, we outline two of these challenges. (1) Quantum programming continues to be a complex art mastered by a select few experts. We suggest that the primary culprit can be pinpointed in the absence of high-level quantum software abstractions which forces developers to work with low-level quantum concepts and reason in terms of matrix multiplications. (2) The scarce collaboration among quantum software engineers resulted in a lack of platform and software interoperability. While a diversity of research proposals fuels scientific progress, it can hinder the development and adoption of innovative technologies, potentially fragmenting the collective efforts and confining them within isolated research groups. We believe that overcoming these issues is crucial for fostering innovation, advancing Quantum Software Engineering, and Quantum Computing as a whole.

Quantum computing is no longer only a scientific interest but is rapidly becoming an industrially available technology that can potentially overcome the limits of classical computation. Over the last years, all major companies have provided frameworks and programming languages that allow developers to create their quantum applications. This shift has led to the definition of a new discipline called quantum software engineering, which is demanded to define novel methods for engineering large-scale quantum applications. While the research community is successfully embracing this call, we notice a lack of systematic investigations into the state of the practice of quantum programming. Understanding the challenges that quantum developers face is vital to precisely define the aims of quantum software engineering. Hence, in this paper, we first mine all the GitHub repositories that make use of the most used quantum programming frameworks currently on the market and then conduct coding analysis sessions to produce a taxonomy of the purposes for which quantum technologies are used. In the second place, we conduct a survey study that involves the contributors of the considered repositories, which aims to elicit the developers' opinions on the current adoption and challenges of quantum programming. On the one hand, the results highlight that the current adoption of quantum programming is still limited. On the other hand, there are many challenges that the software engineering community should carefully consider: these do not strictly pertain to technical concerns but also socio-technical matters.
Abstract Quantum computing is an emerging field in which theoretical principles are being transformed into practical applications, largely due to the efforts of the developer community. In order to ensure that quantum software engineering continues to advance, it is vital to understand the experiences, challenges, and aspirations of developers. This chapter is a continuation of our previous work, which provided a comprehensive survey exploring the adoption patterns and common challenges in quantum software engineering. In addition to the survey, we conducted in-depth, semi-structured interviews with practitioners in the field to gain a deeper and more detailed understanding of their perspectives. Through the interviews and survey findings, we have gained nuanced insights into the motivations, hurdles, and outlook of developers toward the rapidly evolving quantum computing landscape. We describe the research methodology in detail, including the tools and techniques used, in order to provide a comprehensive understanding of the research process. Furthermore, we present critical insights from both the survey and interviews, enriching the narrative with fresh perspectives obtained from the post-publication interviews. This chapter is a blend of academic investigation and real-world practitioner insights, aiming to provide a comprehensive understanding of the current state of quantum software engineering. By illuminating the path for future research and development in this dynamic field, we hope to guide the way toward continued progress and innovation.
This article provides an overview of the current state and future challenges of quantum software engineering as quantum computing transitions from proof-of-concept to potential industrial adoption. While significant progress has been made in quantum hardware and cloud-based execution platforms, the article argues that innovation will depend critically on advances in software tools, programming abstractions, and engineering methodologies. Focusing on the constraints of the Noisy Intermediate-Scale Quantum (NISQ) era, it examines challenges related to hardware heterogeneity, software portability, hybrid classical–quantum architectures, and the lack of mature development environments. The article also highlights the urgent need for a new generation of quantum software engineers and coherent educational programmes, particularly in Europe, to bridge skills gaps and support the long-term evolution toward fault-tolerant quantum computing.
Quantum computing is the latest revolution in computing and will probably come to be seen as an advance as important as the steam engine or the information society. In the last few decades, our understanding of quantum computers has expanded and multiple efforts have been made to create languages, libraries, tools, and environments to facilitate their programming. Nonetheless, quantum computers are complex systems at the bottom of a stack of layers that programmers need to understand. Hence, efforts towards creating quantum programming languages and computing environments that can abstract low-level technology details have become crucial steps to achieve a useful quantum computing technology. However, most of these environments still lack many of the features that would be desirable, such as those outlined in The Talavera Manifesto for Quantum Software Engineering and Programming. For advancing quantum computing, we will need to develop quantum software engineering techniques and tools to ensure the feasibility of this new type of quantum software. To contribute to this goal, this paper provides a review of the main quantum software components and platforms. We also propose a set of quality requirements for the development of quantum software platforms and the conduct of their quality assessment.
Abstract Quantum computing represents a revolutionary computational paradigm with the potential to address challenges beyond classical computers’ capabilities. The development of robust quantum software is indispensable to unlock the full potential of quantum computing. Like classical software, quantum software is expected to be complex and extensive, needing the establishment of a specialized field known as Quantum Software Engineering. Recognizing the regional focus on Latin America within this special issue, we have boarded on an in-depth inquiry encompassing a systematic mapping study of existing literature and a comprehensive survey of experts in the field. This rigorous research effort aims to illuminate the current landscape of Quantum Software Engineering initiatives undertaken by universities, research institutes, and companies across Latin America. This exhaustive study aims to provide information on the progress, challenges, and opportunities in Quantum Software Engineering in the Latin American context. By promoting a more in-depth understanding of cutting-edge developments in this burgeoning field, our research aims to serve as a potential stimulus to initiate pioneering initiatives and encourage collaborative efforts among Latin American researchers.
The quantum computing (QC) field is rapidly moving beyond the realm of pure science to become a commercially viable technology that may be able to overcome the drawbacks of traditional computing. Major technology tycoons have spent in building coding frameworks and hardware to create applications specifically designed for quantum computing over the last few years. The development of QC hardware is accelerating, however, the requirement for software-intensive methodology, approaches, procedures, instruments, roles and responsibilities for creating industrial-focused quantum software applications arises from operationalizing the QC. This paper outlines the concept of quantum software engineering (QSE) life cycle, which entails the engineering of quantum requirements, design, implementation, testing and maintenance of quantum software. This paper notably advocates for collaborative efforts between the industrial community and software engineering research to propose practical solutions to support the complete activities for the development of quantum software. The proposed vision makes it easier for researchers and practitioners to suggest new procedures, reference designs, cutting-edge equipment, and methods for utilizing quantum computers and creating the newest and most advanced quantum software.
