The paper provides a broad overview of the main problems associated with different areas of quantum software engineering (QSE) and highlights recent research developments in this domain. It also discusses future challenges for researchers in QSE for the next decade.

The key highlights and insights are:

1. QSE has emerged as a discipline of its own within software engineering, with growing research interest and dedicated venues. The paper analyzes the increasing number of publications on QSE over the years.

2. Service-Oriented Computing (SOC) principles need to be adapted and redefined for the quantum computing domain to enable seamless integration of classical and quantum components. Challenges include interoperability, platform independence, demand and capacity management, and workforce training.

3. Model-Driven Engineering (MDE) techniques can help raise the abstraction level of quantum software development, but new modeling frameworks, code generation engines, and orchestration tools are required to bridge the gap between classical and quantum computing paradigms.

4. Quantum software testing and debugging require specialized approaches to handle the probabilistic nature of quantum states, limited observability, and hardware constraints. Efficient test oracles, scalable test data generation, and quantum-specific debugging techniques are needed.

5. Quantum programming paradigms need to move beyond low-level circuit composition towards higher-level abstractions and reusable quantum software components. Challenges include optimizing complex quantum circuits, enabling composable and reusable quantum software, and defining suitable data types and operations for quantum computing.

6. Software architecture for hybrid quantum-classical systems must be investigated, including design patterns, architectural decision-making, and maintenance solutions.

7. Quantum software development processes need to be adapted to manage the integration of classical and quantum components, address unique risks, and leverage agile practices and DevOps principles.

How can we develop efficient test oracles for quantum software that balance the need for reliable results and the limited availability of quantum computing resources?

Developing efficient test oracles for quantum software requires a careful balance between ensuring reliable results and optimizing the utilization of limited quantum computing resources. One approach to achieve this balance is to focus on optimizing the test data generation process. This can involve exploring advanced techniques such as search-based testing, combinatorial testing, metamorphic testing, fuzzing, and property-based testing specifically tailored for quantum programs. By leveraging these techniques, test cases can be generated efficiently, covering a wide range of scenarios while minimizing the number of executions required.
Additionally, prioritizing testing on critical test cases can help optimize the testing process. By identifying key test cases that are most likely to reveal faults or errors in the quantum software, resources can be allocated effectively to ensure thorough testing while conserving quantum computing resources. This prioritization can be based on metrics and quality models developed through empirical studies, guiding the selection of test cases that offer the most value in terms of detecting defects.
Furthermore, the development of more efficient test oracles that do not rely solely on multiple executions can help reduce the computational cost of testing quantum software. Techniques such as using state vectors instead of repeated executions, although challenging due to the probabilistic nature of quantum mechanics, can offer a more resource-efficient approach to verifying the correctness of quantum programs. Additionally, exploring the use of quantum state tomography and partial tomography to approximate state vectors can provide valuable insights into the behavior of quantum programs without the need for extensive executions.

How can we overcome the potential barriers to adopting agile and DevOps practices in the context of quantum software development?

The adoption of agile and DevOps practices in the context of quantum software development may face several potential barriers that need to be overcome to ensure successful implementation. One key barrier is the unique nature of quantum computing, which requires specialized tools and methodologies that may not align seamlessly with traditional agile and DevOps frameworks. To address this, organizations can invest in developing quantum-aware toolchains that integrate version control systems, continuous integration/continuous deployment (CI/CD) pipelines, and project management tools tailored to quantum software development.
Another barrier is the limited availability of quantum computing resources, which can impact the scalability and efficiency of agile and DevOps practices in quantum software development. To overcome this challenge, organizations can explore strategies for dynamic resource allocation, contingency planning for quantum hardware failures, and methodologies for evaluating the reliability of quantum algorithms. By implementing adaptive risk management strategies and sustainable scalability approaches, teams can navigate resource constraints and ensure the successful implementation of agile and DevOps practices in quantum software development.
Furthermore, the integration of quantum computing as a service into software development projects can enhance the agility and efficiency of quantum software development processes. By leveraging quantum computing resources available through cloud services, agile teams can access on-demand quantum capabilities, enabling rapid development and deployment of quantum software solutions. This integration can streamline the development lifecycle, facilitate collaboration between quantum and classical software components, and optimize resource utilization for agile and DevOps practices in quantum software development.

Given the inherent differences between classical and quantum computing, what new programming paradigms or language features could be introduced to better support the development of quantum software?

To better support the development of quantum software and address the inherent differences between classical and quantum computing, new programming paradigms and language features can be introduced to enhance the efficiency and effectiveness of quantum programming. Some potential approaches include:

Oracle-Based Quantum Programming: Introducing a paradigm that treats quantum registers as data-type encodings and utilizes oracles to implement basic operations on these registers. This approach can provide a higher level of abstraction and simplify the design of quantum algorithms by encapsulating complex operations as reusable components.

Quantum Types and Abstractions: Developing quantum types that allow programmers to define their own data types and create new abstractions for quantum algorithms. By enabling the definition of custom types and operations on quantum states, programmers can design algorithms that align more closely with the strengths of quantum computing, such as simulating physical processes like chemical reactions.

Composable and Reusable Quantum Software Components: Designing techniques and tools to support the composition and reuse of quantum software components, such as oracles and quantum circuits. By enabling the modular design of quantum algorithms and circuits, developers can create scalable and maintainable quantum software solutions that leverage existing components efficiently.

Higher-Level Abstractions for Quantum Programming: Introducing higher-level abstractions that allow programmers to work with quantum states and operations in a more intuitive and expressive manner. By providing abstractions that hide the complexities of quantum mechanics and circuit design, developers can focus on algorithmic logic and problem-solving, leading to more efficient and error-resistant quantum software development.

By incorporating these new programming paradigms and language features into quantum software development, developers can overcome the challenges posed by the differences between classical and quantum computing, leading to more robust, scalable, and maintainable quantum software solutions.
